Lavenia is the granddaughter of Richard Thomas (my 5th great grandfather) and grand niece of General Philemon Thomas (Richard's brother) whom you've seen mentioned before on this blog and over at The Educated Genealogist.
Joseph Payne Skillman is the son of Christopher Skillman and Henrietta Payne. He made a living as a ferryman. Pleasant Hill is situated at the confluence of the Kansas and Missouri Rivers.

Of course this is before my becoming The Educated Graveyard Rabbit. Not much gets by this Rabbit now!
