Hi Kim, I gave your quiry about the Davin family to a person at Ancestry, a genealogy site, they have done extensive work on the Davin family from your area. Had to leave them a message to contact you here, so make sure to check back. Thought it would be of interest for probably their ancestors. Good Luck!
Kind Regards, Glenda (volunteer) Chicago
PS If you don't here back from them, if you have first names I can look them up for you. Plknowlton@frontier.com
