Found cousin

From a message board, I found another woman searching for the same family name and was contacted by her to see if we were connected. We couldn't find a connection, but kept in touch and she, being even more avid a researcher than I, found another family (name) member and put her in touch with me. This woman is my third cousin, same great grandfather, our immigrant family member and my third cousin now lives in the homestead where my father was born and moved away from when he was four. We are now in touch and have exchanged information for many years. She is the one I mentioned who contacted another third cousin she heard about and he sent me the information I was searching for in Germany, while I was gone. In addition to that, the woman who put us in touch with each other suggested I have my father do a DNA test, since I'm the end of the line in that family and a girl. He did, and we found that, we are related to her family with a common ancestor, for whom we are now both searching.
