Here is the information that I have on my grandfather. I believe that he had some step brother/sisters in Hadley named Sue, Kate, and Mae Dalton and sister Anne and brother Jim but have no detail on them.
I am not sure how I can find connections to existing Daltons or what genetic group he belongs to. Any info would be appreciated. Here is the info I have:
My Grandfather was Dr. John Edward Dalton.
Born 1874 Hadley, Mass
Married 6/6/1899 in Warren, Mass to Ellen Genevieve Gleason
Died 1/21/1962 Natick, Mass
His Father - John Dalton born Ireland; married around 1867 in Ireland believe Tipperary ?
His Mother - Honora Walsh (Welsh) born Ireland
