The list of children for Andrew Peeters has only one son by this name: "6 (6). Wry (William) son of Andrew Peeters, borne the 7 of February 1672" from Ipswich church and parish records. Also "William, sixth child of Andrew Peeters and Mercy Beamsley his wife, born in Ipswich, Febryary 7, 1672, killed by the Indians in Andover August 13, 1696. (No record of marriage, but is said to have married Margaret Russe in 1694, perhaps daughter of John Russ and Deborah Osgood, born in Andover, April 10, 1673?)"
[Note: as can be seen here, "Wry" is used frequently, and as this is a copy, it is probably a misreading of Wm. by the copist, as all the occasions checked, show up in the published records as William.]
