I don't know if there may be a way to look up the entire story. According to birth records, both members of a couple belonged to the same MM, but she was dismissed for marrying out of meeting (according to family records). Next, her mother, grandfather, and great-grandfather were declared out of unity. Two children from the marriage married a brother and sister from Mennonite and Brethren background, the later of the marriages recorded in the same MM. My grandmother and step-grandmother were cousins from this family; another cousin enlisted in WW II and died in a military plane crash in Alaska.
I'll tag on the stranger story of my ancestor who married as Presbyterian, later baptized and proselytized as Roman Catholic; her death record is in Quaker MM and she was buried at her catholic church which was vandalized a few years later.
