I talked with a davenport from new england a couple of years ago and he told me that the davenport name came over with an eastern european future king.I don't recall his name but i think it had henry in it.If i remember correctly he said that it was of german origin,don't know if that is true though.It is somthing to look into .Good Luck,hope this helps. Sincerly, Capt.T.R.Davenport of P.A.
