Roosa surname reunion is scheduled for the second week of July 2005 in Kingston, New York at the Holiday Inn this is a four day event. One common denominator in Roosa/Rosa/Rose seems to be Aldert Heymens Roosa who came to this country in 1600's.
We had a reunion in 2000 and it was very successful.
If you are interested I will send you the information.
If you have a specific question about a Roosa descendent or ancestor I will try and find the answer for you.
