Really a great work, thanks.
Trying to summarize the data, Avery senior married twice:
1) with Florence
2) with Leila G.
He had three child, two son and one doughter, all born in South Carolina.
1) Avery Willis Luther jr (1911)
2) Avery Emma J. (1914)
3) Avery Joseph P. (1915)
There isn't any proof that Avery Willis Luther jr married and had sons, Is It so? Is that right?
