The AGBI is the American Genealogical and Biographical Index, published by the Godfrey Library at Middletown CT. (www.godfrey.org) The library has all the sources listed in the AGBI. The reference is for Mary Jane Elmer, born 1845. The book is Hughes and Allied Families, and there are two pages where she is mentioned. I volunteer at the library every Thursday and will look up the pages for you tomorrow. Diane D. Reid
