Perhaps you should try some spelling variations:
janse van » janse jan (Expand Search)
than van » thanh van (Expand Search), tran van (Expand Search), thien van (Expand Search)
jan van » dang van (Expand Search), tang van (Expand Search), tran van (Expand Search)
jan jan » janse jan (Expand Search), jang jae (Expand Search), kuan jan (Expand Search)
dscornelis » cornelis (Expand Search)
gijsbert » gilbert (Expand Search), ginsberg (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "dscornelis gijsbert gerrit ((((((jan van) OR (than van))) OR (jan jan))) OR (janse van)) steenis~".
• Adding a wildcard symbol may retrieve word variants: dscornelis gijsbert gerrit ((((((jan van) OR (than van))) OR (jan jan))) OR (janse van)) steenis*.
