Hellow Luis, maybe we were relatives. Four different branches came to Argentina in the midle 1800 and had developed a lot.
If you read spanish you may find the different genealogy trees in http://gw.geneanet.org/enriqueorfila
and a short story of our surname and its development in Argentina, and some photos and ....... in http://www.geocities.com/los_orfila
. Let me know if we have any common ancestor.
By the way, if your name is Luis, you shoud speak spanish and in that case, it would be easier for me.
