The site I mentioned is the official site of the archive of Friesland. So there are no connections, just the records. There is one Bouma - Dijkstra record, but not your Henry, it's a Pieter. Did the marriage you mentioned take place in Friesland, or somewhere else ?? I'm wondering about your Henry, in Friesland that should be a Hendrik or something like that.
