I finally contacted her.
She told us that she is the daughter of my grandfather's brother, but a little mystery still persists..we still have identical last names. My father always told me that our last names was misspelled (a "r" instead of a "l), .... my uncles and cousins have a different last name...now I found a branch of my family with the same misspelled last name ??????
I find odd that everyone is busy with Facebook, youtube, games, porn and internet shit, but no one has any curiosity to find out the origins of our family.
Time to do some digging...
