Herman's birth is not public yet. I looked in Delpher to see if the marriage is traceable in there, but no luck there.
Any hint of the names of his parents might help.
Maybe off topic/not related: there is a marriage notification for Herman Th. A. Bax and Louise Baarspul (Victoria B.C. Canada) on Sept 15, 1961 (maybe 1951). cbgverzamelingen.nl
