For me, I like to go to face book and look up family names. I have met some new Wonsey cousins through facebook. The saying goes (according to my grandmother) that if you are a Wonsey, you are related.
Some names are very common and some aren't. Hopkins and Hunt -too many to count! But I like to bug people anyway and ask about their family tree. Most are helpful, even if they only tell me there is no way they are related. Bugging is what keeps me doing genealogy. I had a lot of practice as a child bugging two older sisters! Why stop now?
