If I could have one genealogical wish, it would be to find the marriage book for the Rev. Jonathan Cushing, minister of Dover, NH from 1717-1766. For some odd historical reason, his book of baptisms survives, but his log of marriages must have been misplaced or destroyed. It is not published in the Vital Records of Dover, New Hampshire. How does a church save its baptismal book and not its marriage book?
My ancestors Jonathan and Elizabeth Pinkham have all their children baptized by the Rev. Cushing in Dover, so there's little doubt he married them. However, they leave no probate records and no deeds that shed light on her maiden name. There may be court records, but most of the Strafford County court records of those times are still unprocessed and unindexed in Concord, NH (Live Free or Die--But Too Slow on Organizing Records).
I'm fairly sure I know who she is: the daughter of Richard and Elizabeth (Beard) Plummer. However, no smoking gun has emerged. She's the right age; her daughter uses the Beard name for a son; I can prove the Plummer Genealogy is wrong with who they think Elizabeth's husband was [it was not William Twombly]; there are huge amount of land transactions between Jonathan Pinkham and the Plummers in Rochester, N.H. where they all move.
