I found a small list of early Philyaw marriages in Mobile, AL, and hope they will help someone. Most of the Philyaws in the Mobile/Whistler, AL area during this period were children of David and Margaret A. Philyaw (originally from SC, by way of Butler and Conecuh counties, AL). But I have never seen the first Philyaw female connected to David.
Philyaw, Gertrude to Baucum, William 7/10/1856
Philyaw, John W. to Baucum, Elizabeth 3/31/1857
Philyaw, Sumers D. (actually Simeon Deming) to Williams, Mrs. Gracy (a widow) 08/26/1867
Phylan(?), Mrs. Elizabeth M.(a widow) to Brown, William H. 11/30/1868 I am still trying to confirm that this last one is the Elizabeth Baucum that married John W. nine years earlier.
Hoping that someone will know the Gertrude mentioned... when I found the new Baucum family on the 1860 census, the wife's name was listed as Wealthy and they had a son named William, born in 1857.
