My mom is working on the genealogy of Derby/Darby, she is looking for information on David McDonald/Donald. He was either born in Ireland or maybe Nova Scotia, He died in Boston around the late 1800's or early 1900's. He was married to Catherine Barry who was born 1820, in either Ireland or Canada. Looking for his parents or siblings, they are my Great,Great,Great grandparents.
