Most Common Surnames
Please note that Safari sometimes hangs when attempting to display a chart. So far as I have ascertained the only thing to do in such a case is to completely close Safari. If possible, Safari users, please use an alternative browser if you intend to use the chart features.
I have seen a number of posts on this problem to the Webtrees team. I will check from time to time whether an update to fix it has been posted.
