DONATIONS WELCOME

Although everything is here for you to read and use for free, I have over the last 30 years incurred substantial expenses and if you find anything useful, I would appreciate a donation.

Every single donation, regardless of how trivial it may seem, will be an enormous help. It will help me continue my research to the benefit of everyone working on their family histories.

If you would like to make a donation, you may use the following PayPal link:

Or, you can mail me using the following mailing address. If you are mailing from the U.S., remember to use the correct postage. Thanks.
