Many thanks for your response. Further circumstatial evidence of a family connection: 1 of Thomas FLOYD's sons was named Noah; another of his sons went to LaSalle Co., IL (where Noah LEONARD & his FLOYD wife settled) in the 1860s while seeking employment. Had found no previous FLOYD family connection to that location. I had also theorized [by process of elimination] that Susannah FLOYD was the most likely known candidate to have been Thomas FLOYD's widowed mother & that a Richard FLOYD from earlier census listings was possibly her late husband, but had no idea of her maiden-name or their county of origin in VA. It will take me at least a few days to assemble what FLOYD information I have accumulated over the years, but will send it on when I have it in more coherent order.
