Yes, there's no doubt you and Marilyn (Aldrich) Mason, my wife, are cousins.She descended from William, Emeline's brother, through (2)Crowell Sanford, (3)Alvin, and finally her father (4)James.
As for Jonathan being Edward's father, that now seems certain.He (Jonathan) moved from somewhere with Edward and Peter to Rose, Wayne County, NY)(at that time being Walcott, Cayuga County, NY) from somewhere else.He bought 130 acres of land from an English aristocrat and settled there in January of 1813. In November of that same year he sold 100 acres to Edward Aldrich, and one side of the land sold was alongside Peter Aldrich's land.
In a book called "Rose Neighborhood Sketches," Jonathan is called, "Old Micajah."But there is no doubt about his being the same man as Jonathan.The book names his sons Edward and Peter.
As to Edward being born in Rhode Island, I haven't heard that before and I kind of doubt it unless you're sure of your sources.I think it more likely that he was born in Kingsbury, Washington County, but I can't prove that since most of the early records for that town burned up in a fire.At any rate, this is what I have, Dawn.Blessings to you - Chuck Mason
