Can you point me to the Trinity Co. Land records you mention? I know there was a land grant in Houston Co. made to William W. Slay about 1840. I have ordered copies of the records. I have other bits and pieces of information about Francis' parents which are at least consistant with the connection to William W. Slay family. Since Francis Marion A. Slay was my Greatgrandmother, establishing the proper link link to the large amount of Slay data is very important to me.
