Will of Ebenezer Billings, dated 22 Jan 1717/18, proved 6 Mar 1717/18 [Suffolk Probate, vol. 20, p. 298], mentions unnamed wife and "all of his thirteen children". "Two youngest sons Bezaleel and Elkanah" executors.
[Note: this article appears to be confused about Ebenezer's birth. At the top of page 92:264, it says he was baptized with Samuel on "26-5-1651" and at the bottom of page 92:264, it says he was born about 1656. This is clearly not possible. The Dorchester Church Records actually contains two baptisms of Ebenezer Billings, suggesting there were two separate sons named Ebenezer, and the list of children in this article has a gap from 1651 to late 1657 that would suggest this might be true. On p. 161 of the church records, "Ebinezer" is baptized with Samuell on "26 (8) 1651" and that Ebenezer presumably died as an infant, because on p. 167, "Ebinezer" is again baptized on 6 Jan 1655/56. Incidentally, the date specified in this article, "26-5-1651", appears to be a misreading of the records. As printed in the published records, the record says 8 and appears to be in perfect date order, whereas month 5 would be out of order. Also, Samuel and Ebenezer are baptized at the same time as a John Trescott, whom Dorchester records said was born "21 : 8 : 1651" and this John Trescott wouldn't have been able to have been baptized on 26 - 5 - 1651. The article cites as the source of this date something it calls EJB (a collection of corrections to the "Thayer Family Memorial" in NEHGS library), not the church records themselves.]
