hello i may be part of your family i dont really know i live in the united states and my grand parents moved for poland during world war 1
my grandfather changed his sons my dads last name from jacewicz to jacewitz perhaps for pronunication
my great grand father who moved here was benjamin jacewicz and my grandfather and grandmother were chester and regina jacewicz
well anyways just wanted to say high because theres no one with jacewitz as their last name except us here in the us because of the change and well i see you all with jacewicz which is what our last name used to be so hello if we are part of the same familty nice to meet you and best wishes even so if we just share a common name or otherwise

peace
Daniel
