On a global scale is best site is World Profiler – this site which is run by a university in the UK has had issues for a while. The site takes a surname, asks for an email address and the gender of the requester, these are for statistical purposes. The site also uses Adobe Flash Player and coupled with the statistical material it often sends some browsers into a panic!
I have used the site initially successfully with Chrome, then Microsoft Edge without issue. Sadly the site is, at the time of writing (23 May 2019) unavailable and I hope it returns, which is why I have left the link in place. If you find it working, please do leave me a comment! In the meantime, you can see an example below for the surname of Orlando
