In many genealogies, Mary Lovet is shown as the first wife of John Leavitt, Sr. She and John had 5 children, and she died July 3, 1646. Anderson (Vol IV - I-L, pg 274) says there are no sources for what her name actually was, and whether her first name was even Mary. The conjecture was based on a Dorchester church record of a Mary Lovett being admitted about 1638. However, he goes on to say that the Leavitt's weren't still living in Dorchester as of that date, so the record is "almost certainly not the first wife" of John Leavitt.
In light of this, it would likely be best for her name to be Unknown Unknown, but how do we indicate that she is the same person as "Mary Lovet"? Is the best thing to do to add a Preferred Name of Mary Lovet, add a married name of Leavitt, and leave all the other name fields Unknown?
UPDATE: There had been a merge pending of Lovet-17 into Lovet-9, but, my gut feeling is that they both need to be merged into Unknown, so I removed the merge.
