Diane, You mentioned in your post that you have John T. Humphrey's book "Montgomery County Births, 1682-1800". I have a very common name, but particular families with no dates yet for any of the births. I'd be grateful if you could check for them. Thomas DAVIS & wife Elinor ? had children Thomas, David, Elinor (m Jones) and Elizabeth (m Gordon). They were in Hatfield Montgomery county possibly as early as 1724, definitely by 1740. I don't know where they came from. Thomas died in 1777 and the girls were married, so births would be mid-1700's, anywhere in Phila general area. David DAVIS m Elizabeth ? and had children John, Thomas, Henry, Archibald, David, Elizabeth (m Abraham Garner) and Mary. Of David's children, all except John were minors in 1815, when guardians were appointed for them. Thomas DAVIS (wife unknown) had children John, David, James, Eleanor (m Peter BURK), Thomas, Isabella (m John HARTZLE), Margaretta. All of these children were adults in father's estate settlement of 1815. Both men died in 1815, and their estate records and property were in Hatfield Twp, Montgomery Co. Thanks in advance, Edie
