My great grandfather's last name is Estabrook. He lived in Wisconsin in the 1890's. After the death of his father, due to complications arising from an amputation, his mother married a McKittrick (this would likely have happened in the 1890's. Not sure if this is any relation to you all, and unfortunately I do not have first names. Do you have any information about any McKittrick's living in WI in the 1890's who may have married a widowed Ms. Estabrook?
Thanks,
Daniel
