A Mills and Kendall Family History (2002) by Helen Schatvet Ullmann, CG, FASG, quotes the 1658 will of Nicholas Tanner of Rustdorp, New Netherland (later Jamaica, Queens, New York):
My will is that Bethia Mills shall have a cow and a calfe, and that she and her mother shall have ten pounds more betwixt them, to buy them clothes with.... Zacharias Mills shall have a calf.... George Mills is to have all my cloathing except as above given.
Ullmann writes, "Many have assumed that this was a daughter of Nicholas Tanner, but the documents relating to Nicholas Tanner's estate do not show this clearly at all."
Tanner does not state any relationship between himself and the Mills family, and these bequests are included among a long list of other legacies to several apparently-unrelated neighbors and associates.
George's wife's name is known to be Rebecca, thanks to a deed dated March 24, 1681/2. However, the evidence for LNAB Tanner would seem to be insufficient.
There is most definitely no evidence whatsoever that Rebecca was a daughter of John Tanner and Joan Hadnam, who are currently connected as her parents but will probably be removed by the time you read this. ;)
Should Rebecca's LNAB be changed from Tanner to Unknown? I believe yes.
Should Rebecca's current parents be detached? Let's go with yes.
Is there a Project, perhaps New Netherlands, who might like to PPP Rebecca and her husband George and their children?
