Re: Catherine King and Prosper Tacey, Jr
I was sent something a few months ago that I think you might like. It turns out that there is a biography on her from a book printed in the Netherlands that fills in many of your missing gaps. It also gives the background on Adriana (the father you have listed is her stepfather). If you're interested, email me and I'll happily pass it along.
Also, we're trying to create a living history website on the Tacey family. If you're interested in joining the project, let me know.
