Dear Pat, See if there is a listing for this marriage of-- Elizabeth G.[BARLOW],also called Libbie of Dutchess Co.-- UNK which village, and Addison Vail SMITH of Stanford,NY. or Clinton Corners. A child was born 07.DEC.1880 in Millbrook so the marriage was preceding that date and family-lore says the marriage was in 1880. That may be helpful. Thank you for looking up all these marriages for us.. Charlotte J. Sheldon
