I am searching for any information on my gt-grandfather Thomas Waldron. According to my grandmother's birth certificate he was born in Haverstraw, NY around 1856-7. According to one cousin, the family tree was traced my her mother. Unfortunately that research has been lost, except for a copy of someone ele's research about a Jacob Waldron descended from Resolved Waldron of Holland. Thomas was supposedly a twin, or in a family with a twin. There was a Susan Waldron who was his sister, and she either lived in Yonkers, NY or there was another close relative living in Yonkers. Thomas died somewhere between 1893 and 1899. He married Mary Cunningham somewhere around 1890. They lived in NYC in 1890 and were both in PA in 1893, based on where their two daughters were born.
