Elaine, CORRECTION: Eva did not have the surname of WEBSTER.Sorry for my error.However, her name was Mrs. Eva L. SHERMAN REED HARRIS ALEXANDER.
I have read a scan of a newspaper article from "The Phoenix" (Brattleboro, VT) Jan. 14, 1910, which states that Mrs. E.S. Alexander is the sister of Mrs. Mowry Lynde. The end.
Mrs. Mowry LYNDE was nee Mary A. REED. Eva L. SHERMAN was adopted by the REED family. Her first husband was Mr. HARRIS.
1st generation [earliest] ALEXANDER Mariah¹ living with Edmund S. in 1900 and 1910, 2nd generation Edmund S. ALEXANDER² is listed as divorced in the 1900 U.S. census living in Colrain, Franklin Co., MA [Massachusetts].
