re: Alvah's grandfather XXXXX XXXXX. Is there any further information on him? i.e. where was he from? Maybe immigrated from another country?
Hello,Welcome and thanks for your question. William was born 1742 in Newton, Massachusetts. The Clarks were in Massachusetts for a long time before that. Ultimately they came from England.
