This is my personal genealogy hobby site. The data contained here has been gathered through 20 years of genealogy. Some of it is my research, much of it has been shared with me.

DISCLAIMER: This is my speculative data. I've verified very little of it. Use it for hints and pointers, but do your own research!

It costs me over $50 (US) a month to have this data on the web, so your support would be appreciated! If clicking on advertisments is not your thing, please consider a donation!
