Dear Junelle, Reuben Chase is my 5th Great-grandfather. As far as I am aware, Elizabeth's surname has never been discovered, and probably does not exist in any published genealogy. I have never even heard of anyone speculating on what it may have been. Please, if I am wrong, I sure would like to know! I, myself, have viewed Reuben's will, as well as the usual Loyalist stuff - ship's manifest, etc.. and I have only seen her referenced as either Elizabeth Chase or Mrs. Reuben Chase. I have never seen the marriage record - perhaps there was none found. Best of luck, Lisa Zajkowski
