Henry Van De Water Family

Henry Van De Water was born in New York and was married to Polly. I do not have any dates or Polly's maiden name. They had a son James Henry born in New York and married to Kathryn Coakley of Ireland. She was the daughter of Jerimiah Michael Coakley and Marguarita Mary Condon both from Ireland. James and Kathryn had two sons, Roscoe Conklling and James Henry both born in New York. Roscoe was my grandfather and was born in 1877. I am looking for any information and am willing to share what I have.
