I'll try and stick to the convention of describing left or right in the picture from our perspective viewing the picture rather than from the perspective of the individuals in the picture (which of course would be the other way around).
In front of the porch or sitting on the steps (from the left)
Uncle Harmon (John Harmon Overstreet) is the leftmost person in the picture. He is partly cut off in the picture wearing a white shirt and dark trousers.
Aunt Alice my other mother (Alice Artemsia Overstreet née Arms) is to the right of her husband Uncle Harmon. She's wearing a hat (she loved hats and sun bonnets) and is wearing a yellow print dress.
Cousin Peggy (Peggy Brown née Overstreet) sitting in front of Harmon and Alice is their eldest granddaughter Peggy. She's holding her baby Hanna Boles. Peggy is Frances and Mitchell's daughter and Jane Helen, Henry, and Lee Angell's sister.
Uncle Amos (Amos Arms) standing in the red shirt and grey trousers next to Aunt Alice
Judy Arms (I think) standing next to her fiancé or recently become husband Walter Lee Arms.
The child in front of them in pink shorts (I'm really guessing here) is maybe Amanda Parsons?
To the right of Walter Lee is a Aunt Lorene Arms (Amos wife) holding Celest Watson (Sorry couldn't recall either [fortunately Charlene knew], it'll probably be that way for me with most of the children too).
Aunt Edith (Edith Bilbrey née Arms) is standing to her right. Her husband Charlie Bilbrey is sitting to the left behind her on the porch and my mother (Laura Lee Mayo née Arms) is sitting on the porch behind her to the right.
Aunt Helen (Helen Wells née Arms) is standing to the right in the light blue blouse and white skirt.
?Robert (or James) Parsons? Standing to the right of Aunt Helen is Lura Dean's son (who looks a whole lot like me in this picture as I looked when I was his age)
Jane Helen (Jane Helen Scott née Overstreet) (I should know Jane Helen's married name, but I can't remember). [Charlene had the information, her husband was Larry Scott, I had heard from mother that she had gotten married but I don't believe that I ever had the chance to meet him and it is so sad to hear from Charlene that he has passed away].
Lee Angell ? née Overstreet (I think Lee Angell's married name is Poindexter. I'm not sure how she spells her name as I never wrote it growing up, I've just heard it, so if you know and I've gotten it wrong please let me know). [Charlene didn't correct me on Lee Angell's married name so I guess I may have gotten it correct?]
OK here please cut me a little slack because Brenda Lee Stubblefield née Bilbrey and Charlene Groves née Bilbrey were more my brother and sister's age and I was the little kid that the older ones didn't want to be around to annoy them so I always get mixed up which is which so, I think the guy with the blond hair, white shirt and blue pants is (one of their) husband and I think the three behind them who aren't my father or me are (the other of Brenda Lee and Charlene)'s husband, Lura Dean's husband, and Peggy's husband, but I'm mostly guessing here. [Charlene provided the correct answer as she was able to recognize her husband :) He's Gary Groves, and she says he has pretty red hair like the Mayos (thank you)]
Ok next to him in the red and red and white striped outfit is Brenda Lee or (Charlene see above) [Charlene recognized herself too (which is better than I did on myself), so this is Charlene Groves née Bilbrey]
And so … next to her is Brenda Lee Stubblefield née Bilbrey.
To the right in the pink dress or blouse is Lura Dean Parsons née Arms
Sitting on the steps to the right is Frances Overstreet née Hix (I haven't ever seen Hix spelled so I'm just guessing here) and next to her on the steps is my cousin and her husband Mitchell Overstreet.
for the kids sitting in front this is close to pure fantasy (I'm trying to guess-construct who is who of the kids from Charlene's notes on the great grand children photo [see post]), but here goes:
Warren Arms in white shirt and dark trousers
Brack Stubblefield in blue and red striped tank top (Charlene or Brenda Lee's son see above, I'm thinking Brenda but I'm probably wrong) [Hey, I was right, Charlene confirmed this is Brack, Brenda Lee's eldest].
?Pam Watson's brother (???Donnie???) is kneeling next to the dog in the blue tank top with red trim
???James (or Robert) Parsons??? sitting cross legged with his head in his hands
On the porch
Kids standing on front of porch
Brian ?
Pam Watson
Tara ?
Rama Arms
and sitting down to the right of Rama in dark glasses is Uncle Charlie
Standing behind the children I believe are Amos' children (older-my brother and sister's ageish so guessing again here) Billie June, Thomas Edward Arms and his wife.
To the right behind Rama Arms is Josephine Arms, Walter Arms' second wife and to the right of her right behind Uncle Charlie is Walter Arms.
The five guys to the right of Walter between the next two pillars include my father and me and three other guys who (I'm mostly guessing here) are Charlene (I think or possibly Brenda Lee's) husband (Groves or Stubblefield), Lura Dean's husband (Parsons) and Peggy's husband (??Clay?? Brown). [Charlene has identified these correctly too. Bill Parsons (Lura Dean's husband) is the leftmost of these 5 near the left pillar in the white shirt with the big blue stripe. Clyde Brown (Peggy's husband) is to the right of Bill in what looks to be a light blue or grey shirt. To his right with the camera around his neck is my father Ronald Ira Mayo (my mother Laura Lee's husband). Jerry Stubblefield (Brenda Lee's husband) in the white button down shirt is standing toward the front of the porch to the right of father. To Jerry's right in the yellow shirt is me.
My father (Ronald I. Mayo I) is the one in the middle with the Argus camera around his neck and I'm the one on the far right in the yellow shirt leaning against the pillar. (I think I at least got me right this time …)
Obviously grandfather and grandmother were there in spirit if not in body:
Archie Thomas Arms ("Father", grandfather, Mr A.T. Arms, Mr Arms) I was named for him.
Dayse Lucretia Arms née Stone (grandmother)
Charlene also mentioned some of the relatives who were not in the picture, I believe some of them may have been there that day but not around when this picture was taken.
Here they are:
Uncle Dewey Wells (Aunt Helen's husband)
Dayse Lucille Overstreet (Aunt Alice's daughter)
Fay Donald Watson (Billie June's husband)
Sharon Edith and Ronald Ira III(?) Mayo - Were they at Bible camp?
[my sister and brother Laura Lee's oldest children, Ronny is II (III is my nephew, Ronald II's son, who wasn't born until November of 1977) , Ronald Ira Mayo II was married and working in Ohio when this picture was taken. My sister Sharon Edith Mathias née Mayo was in Ohio too awaiting the arrival of her 2nd child Cassie Belle Mathias who was born November 1977 too. Sharon was named for Aunt Edith]
Henry Mitchell Overstreet (Mitchel's son)
Bobby Burton and Lester Earl Arms (Uncle Walter's sons)
