my samson line

i have adequate documentation that a man called samson anthony samson is actually one of my ancestors
the doc stated that he and another 3 brothers lived in Leyden Holland and adopte the patronyme Samson at 1811' as registrated by the rotterdam population service

my concern is to find out from where to came to leyden, since samson was not a typical jewish name in the netherlands at this time.
the samson line led me to my gr. grand father abraham samson, born in amsterdam
can somebody provide info regarding the origin of the samsons at leyden
