I don't have any information for you on your Thomas Snead/Abi Hendricks or Perry Snead, as such -- however, there are some parallels or similarities I'm seeing with my Thomas Snead (my great-grandfather).Here is my info:
Thomas Caswell Snead born to Benjamin Edward Snead and Caroline Armstrong in Arkansas October 29, 1853.
We apparently have some Missouri connection because his brother, George Albert was born in Joplin, MO Dec 24, 1865.
Also,his brother, Harrison E., seems to have been in MO.Thomas Caswell's siblings (that I know of) were:Priscilla E., b. about Aug 1850 in Arkansas; Harrison E., b. about 1851 in AR; James C., b. about 1855 in AR; Ann b. about 1858 in AR; Benjamin b. about 1862 in AR; George Albert b. Dec 24, 1865 in Joplin, MO.
If you can make any connection, I sure would like to hear from you.I'm stuck at Thomas Caswell's father and mother (Benjamin Edward b. May 13, 1823 maybe near Richmond, VA. and Caroline Armstrong b. about 1824 near Nashville, TN).I've not been able to go any further back than those two and as you can see, I don't have definite info on them.
