Mayhew died in 1960 of injuries he sustained in a car accident that he was not able to recover from. Notes Not much is known about Ariaantje Oosterhout, but she was evidently descended from a prominent Dutch family. One indication is that she is descended from Anneke Jans Bogardus, who was the wife of Pastor Evarardus Bogardus, the 2nd pastor of the church in New Amsterdam, now New York City. One note I have says that Anneke was 'owner of 60 acres in the business portion of NYC'. The land in question was in Lower Manhatten and by the 1860's was worth a lot of money.
Further research is needed here, for sure.
