The Jane Dunham and Lindsey William Dunham connection needs more research! The father of Lindsey is William. The mother of Lindsey is Sarah. This does not compute with what I have on Jane. I do know that both were working together N.Y. in the early 1800s and Jane and husband, Elisha Couch purchased land from Lindsey. corrected 27 January 2014
