This is really minor.
On the page for the name Anke it says it is a variation of Agnes. A link on the page leads to a list of "Anne's International Variations". Also there is a link to Ophelie on the page for Ophelia, but it just goes to the "Search for Names" page.
Thanks for pointing out these issues. The problem is with the accents -- nameberry's database gets confused by them. I created new extended entries for unaccented Siobahn and Ophelie to address (somewhat, anyway).
