I am in hopes that you can provide additional information and answer several questions relating to Anna Rowland's parents, Isaac and Alida "Olive" Francisco.
My research shows the following:
Isaac Rowland b 1776, d 26 June 1857, aged 81y, in Milton, Saratoga County New York; burial North Milton (old Boyce) Cemetery.He left a will that names heirs, one of whom is Anna Weatherwax; also named is Henry VanderCook Weatherwax.
This will identifies his wife as Mary Tobey, daughter of Stephen Tobey, late of Lee, Berkshire County, Massachusetts.
Mary Tobey Rowland, wife of Isaac Rowland, b 14 Aug 1796 in Lee, Berkshire, Massachusetts, d 18 Nov 1856, Milton, Saratoga, New York; buried North Milton Cemetery with Isaac.The Bixby Cemetery transcription for this cemetery, notes her birth year as 1776, with note that the "information came from Cornelius Durkee 1878 cemetery report, stone down partly buried badly eroded".As the 1850 census shows Isaac aged 74y and Mary as 54y born Massachusetts, I believe that the birth year 1776 is in error as her birth is recorded in the Lee, Berkshire county vital records as 14 Aug 1796 (father Stephen and mother Lydia).
Olive Francisco Peek, widow of Isaac Rowland and wife of Harmonus Peek, b 12 Sept 1789, d 21 Nov 1859, aged 79y 2m 6d, buried West Glenville Methodist Cemetery, Schenectady County, New York.
Harmanus Peek, b 24 Jun 1781, d 27 Sept 1838, aged 57y 3m 3da, buried Vale Cemetery, Schenectady, New York.He and Olive had son, James H. Peek, born 31 Oct 1807, died 1872, buried beside Olive.This indicates that Olive and Harmanus were married about 1806 and as he died 1838, she therefore must have married Isaac Rowland later in life, ie, after 1856 when his wife, Mary Tobey, died.
Lydia Rowland, wife of Isaac Rowland, b 1780, d 29 Sept 1840, aged 60y, buried St. John's Cem, Saratoga County, New York.Might this be Isaac's first wife, before Mary Tobey?Might she be Alida Francisco, the daughter of Rev. Cornelius Francisco and Anna Demarest?Could she be known as Lydia and not Olive?
Isaac and Lydia had daughter, Marla or Mary, b 1807, d 30 Nov 1825, aged 18y 2m 12d buried in St. John's Cemetery with mother, Lydia.
Perhaps you have additional research that can answer several of these questions?
Do you have a listing of siblings for Anna Rowland Weatherwax?
I would like to exchange information on these families and will look forward to hearing from you.
