I received a link to this website this morning from a friend and played around with it a bit this morning. What it does is statistically calculate how many people in the US have your name (first, last, and both). Here are the stats for my family:
Joseph: 9 J H in the US and Joseph is ranked #10th for first names
Heather: 2 H H in the US and Heather is #104th
Jase: there are no other Jase's and Jase isn't even in the database (which they say means it is relatively uncommon)
Meghan: there are no other M H and Meghan is #800
So how many of you are there in the US?
