Making connections with individuals and families makes it all extremely worthwhile.
I have been in contact with first, second and third cousins I didn't even know existed. They had information I didn't and visa versa so, we swapped and bother were very happy to find out more history of the family or individual in our tree. Actually, the jack pot is when you connect with someone who has a picture of an ancestor that you have never seen before!
