Yes I have some info on Willem Karhof born 1673
living in Skien, Telemark Norway. He was not a Norwegian
but an emigrant, from Germany (Frieoythe) with close ties
to Holland. He and his son Joost sent a letter of Credit
to a Notary in HOORN (nETHERLANDS).
He was a Stadschirurg, (Barber).
Please contact me for exchange of further info Thanks=
