I am a direct descendant of Elisha's son George Harrison. DNA has this line coming from the 7+2 Alexanders who emigrated from Ireland. I am still trying to bridge the gap from Elijah, Elisha's father, on back to the 7+2. In my research I came across the following address which takes you to "Descendants of Elijah Alexander", who is Elisha's father: http://freepages.genealogy.rootsweb.ancestry.com/~guinevere60/alexander/pafx.htmhttp://freepages.genealogy.rootsweb.ancestry.com/~guinevere60/alexander/pafx.htm
This contains valuable information backed up with documentation on Elijah and his multiple descendants. The entry on William is:
William ALEXANDER was born about 1867 in AR.
CENSUS: This maybe the right William Alexander - 1900 Franklin Co, TX, ED 40, JP 1, pg 21b (37) 35/358 William E Alexander Head W M Apr 1868 32 M 12 AR TN AR Farmer Tinny Wife W F Feb 1870 30 M 12 6/5 AR AR IT Andrew Son W M July 1889 10 S TX AR AR Ollie Son W M Jun 1891 8 S TX AR AR Otus Son W M Dec 1894 5 S TX AR AR Omie B Dau W F Dec 1894 5 S TX AR AR
I hope this will help and if anyone has information on Elijah's father, I would appreciate it.
