Arthur Acheson, Ardsley-on-Hudson

Would like to hear from any descendents of Arthur Acheson, Shakespeare scholar, of Ardsley-on-Hudson, New York State. He had two sons. Arthur Murray Acheson was born on 27 June,1890 in Omaha, Nebraska, and fought in France in WW1. Alexander Glen Acheson the second son, perhaps born two or three years after Arthur, was living with his mother Georgina Acheson in Irvington-on-Hudson, NY in 1936 and was probably not married. Daughter Elizabeth(Betsy) did marry, someone in US-Navy. Are you a descendent of one of these children of Arthur and Georgina Acheson? If you are or know of them, I would be pleased to hear from you.
