Welcome to the state of Pennsylvania!

We hope to present quality information and a collaborative environment that will help you discover your family history and ancestors. Please consider joining us. Whether you wish to help with this state, one of its counties, or with another part of our history, they have a fun team.

While you are here I hope you will consider becoming a county coordinator or even just provide some of your family historical information to this site. Please consider it. Participation isn't hard and I am willing to help you in any way I can. What is most important, is that you want to help others by putting historical and genealogical information on the web. I am sure that you have something valuable to offer. Your family research, biographies, histories, pictures or other information would be so helpful to others. Please let me know if you have any questions, or if would like to help in any way. If you don't want to sponsor a county, maybe you have some information you would like to share, that is a great thing too. Please contact me so we can find the right way for you to participate. We would love to have you join our team. Send a message by going to the About Us page and submitting a note concerning your interest. Please be sure to describe what you are interested in.

The entire site is open for reading; however, I hope you will consider becoming a Member.
