Perhaps you should try some spelling variations:
irene mah » irene m, irene a
siew hong » siew keong, siew kheng, siew hoey
dan dana » dan data, mann dana, dan doa
wang dan » wang yan, wang ban, wang yidan
wang hui » wang hua, wang zhi, wang wei
yang jui » yang judy, yang di, yang xi
sek hong » seok hong, le hong

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((dan dana) OR (wang dan)) ((wang hui) OR (yang jui)) irene mah ((siew hong) OR (sek hong)) vu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dan dana) or (wang dan)) ((wang hui) or (yang jui)) irene mah ((siew hong) OR (sek hong)) vu ;~".
• Adding a wildcard symbol may retrieve word variants: ((dan dana) or (wang dan)) ((wang hui) or (yang jui)) irene mah ((siew hong) OR (sek hong)) vu ;*.
