Researching my (mostly Dutch) ancestors I come across one William Blackmore, born in England 1680 (according to Dutch Reformed Church data), who married a Dutch woman and apparently spent the rest of his life in the Netherlands.
He was buried at Rotterdam-Kralingen cemetery on 15-10-1738. He married Rebekka Kruisweg (or Kruiswech) on 15-11-1706 in the city of Gorinchem, Holland. They had at least one son, Daniel, born Gorinchem 1712, buried Rotterdam-Kralingen 1792. William was my great-grandfather 6 times removed. His burial certificate reads "Willem Blakmoer" which suggests that he was really settled in Holland. He and his descendants all used the "dutchified" surname of Blakmoor or Blakmoer. The cities of Gorinchem and Rotterdam both had important harbours at the time and not much else, which means that William was probably a sailor.
My question is: Is there anybody out there with a missing sailor in their genealogy named William Blackmore, born 1680 in England, possibly known to have settled in Holland?
