I found this old message on the board. I have a Johannes Berghoffer (Berghofer) mentioned in the web-site of "niet-joodse Spier families". This Johannes married a Grietje de Vette in AMsterdam and had a daugther, Maria Elizabeth, as well as two sons, Johannes and Frans Jacob. Could you confirm whether this is the same Johannes Berghofer from Horinghausen mentioned in your message? If so, is there anything known about his ancestry?
