You have as much information about Mary's marriage to Warren Estabrook as I do. If you want, She married Charles H. Jellings on February 13, 1885 in Poynette, WI. They had two children that lived: John Albert, Born 9/20/1887 in WI and Minnie S. born 4/25/1893. They had twin daughters that died at birth 4/5/1894. I do not believe they named them. (At least I haven't found names.
Do you have a birth & death date for Isabelle Jane and a death date for Warren?
Thank you for responding.
