Jackie, sounds like your been doing some detective work! I doubt that Margaret was born in Rhode Island.The whole family seems to have been born on the family homestead outside of Caledonia,Livingston Co. New York.Although I don't have any proof Rhode Island doesn't seem to fit! I will recheck Albert McVean's work to see if he has her listed. The death date of 1896 for Margaret is listed on the International Genealogical Index (LDS site).The date was contributed in 1991 by a member of the Church. It seems I have several Andrew's listed on my site but I have not done any research on this family. Many of the McVean's were buried in the Mumford Rural Cemetery, Wheatland, Monroe County, New York. But I have not found where this family was buried.
