I am trying to locate any info on my grandfather who was born approx. 1900. He married Mary Chambers approx. 1920. They lived in Brooklyn, N.Y. My mother seemed to think that his family might have been in/come through Canada, but no leads in that theory. Don't know if connection to McDonnells of Kilrush, Co. Clare is on Adair or Chambers side but used to receive a lot of correspondence from them. Thanks for any help.
