well from the last email i received from mickie, I think she is on the right track.I think you are right about the Book of Dow, Looked at it yesterday, what a mess of a system. Don't think we are in there. If even under one of the many Richards. there is a Richard Arthur in the index but can not locate him in the main body of the work.
therefore the place to look is in the passanger list for immigration.
did the Dutch Dow family come over at or about the same time as the Nevius family? Do you have access through a Lib. to P.William FILBY "Passanger and Immigration List Index"? check there for starters.
