Hi Virginia,I hate to tell you this, but not everything is going to be found on the internet.Now comes the time for you to start hunting for records.Do you know when and where Wade died?If so, you can obtain a copy of his death certificate, which should show the names of his parents, including his mother's maiden name, if the informant had that knowledge.
Now, Wade is still alive and on the Johnson Co, TX 1930 census, if he lived long enough to apply for a Soc Sec card, you can obtain a copy of the application he filled out.It should give the names of his parents, residence at the time he applied and other data, too.
Do you know when and where William died?If not, contact the TX State Archives in Austin, they have a TX state wide death index 1903-1940 and should be able to give you county and full date of death for William.Then you can obtain a copy of his death certificate, too.
Have you checked into land records?If William sold any land when his wife was alive, she will have to relinquish her dower right and at least her given name will appear.Look for final sale of his land, his heirs will have to sign off to give clear title to the buyer and you might find he has other children besides Wade.Good way to pick up married names of any daughters.You then can go looking for anyone working on their lines.
Family stories often begin with a grain of truth and then take on spins.Maybe it was William's father that actually had the accident with a child, maybe changed his name -- maybe not.
I went to the McGehee GenForum, in the Search this Forum box I typed Zulah, found a lady who is a descendant of Zulah's son Roland, has photo of Zulah -- bad news her message history shows she hasn't posted anything since 2001, but I would post a response, see if you get a reply.Also, send her a direct email, if it bounces back, she may not be alive any longer.
Post a query of your own on that site, too.
I see you posted on the Harper forum, did you do a search?Not only is the lady from the McGehee forum there, but a man who knows full name of William's wife and thathe was a school teacher in Barnsville, TX.That would be Johnson Co, TX, and since his son Wade went back there by 1920, I wouldn't think William was wanted for murder.Also, this man says Wade was an only child.Lots out there to find and sort through.
By the way, Ancestry.com does not have everything.Have you tried Rootsweb World Connect.Of course, it's owned by Ancestry, practically everything is now a days.But, this is information submitted by other resarchers.You need toprove what they show, some have errors.Someone has Zulah.Always good to contact others, you never know when they might have run across something that isn't their own direct line, but is tied into it.
