I have been able to find very little information regarding William Calvert. The one I have was born 1846 in England. He was married to Mary Hodgson who may have been previously married, born 1845 in Rhode Island. Their children were Ella L. Frazier (born 1866, NH), Ellen Calvert (born 9Feb1872 in Fall River, MA [from birth record]), Mary E. Calvert (my great grandmother born Sept 1874 presumably in Fall River), and Sarah E. Calvert (born 1877 also born in Mass, presumably Fall River). Most of this information comes from 1880 census records. I also have Mary Calvert's marriage record (to Alexis Saucier) and Ellen Calvert's birth record. Thus far, I have not been able to find any other records though I hope to get back there to the Rhode Island archives (many Fall River residents went to Providence for health care at that time) I also want to check the cemetaries for possible leads. I don't know if any of this helps you or connects to your information but if it does, please let me know. Frances Taylor
