I was unable to send you an email with a reply, so I shall post it here. I have some information that fits into your inquiry about Larkin Smith Towles. Specifically, I have a couple of compilations (with footnotes and sources) about the descendants of Henry Towles and of Larkin Chew. Each is about 150 single spaces pages, and I can send them to you in Adobe Acrobat format or Word for Windows. By the way, he was named for Larkin Smith, a cavalry captain in the Revolution , Speaker of the Virginia house of Delegates, and later customs collector in Norfolk, Virginia. Larkin Smith was a brother of Mary Beverley Smith, who married Col. Thomas Towles (father of the Henry Towles who married Sallie Bedford). Oh, there are a couple of people named Larkin Smith Towles. Col. Thomas Towles had a son named Larkin Smith Towles and Henry Towles had a son named Larkin Smith Towles. Because Larkin Smith was such an important fellow, there are also Larkin Smith Thompson and Larkin Smith Slaughter -- descendants of Col. Towles and Mary Smith.
Let me know whether your email will allow you to receive attachments that are about 750 kilobytes, and whether you would prefer Adobe Acrobat or Word for Windows format.
