Hi,
I do not know any of these people but you really ought to get a membership at Ancestry.com. That is where I found out loads of information on my husbands people. I had previously not known any of them as my husband believed they were all dead. This was not the case and I found his sister still living. Ancestry.com is a great site. The membership cost is $155 a year, but I am sharing with a couple of friends of mine so that knocks down the cost and they can look up information on their families too.
You can post ancestry information there and request information. You might want to check the site out. You can do search by names too. It is really good.
Also, I work with a private research company. If you can not find the information you are looking for, we can. We work at a very reasonable rate that shall be discussed at time of employing.
We are: http://www.lostbranches.com
Check out our homesite for the types of work we do.
Have a great day,
Joyce Sanders
