Looking for info about the town and it's inhabitors.

I am looking for anyone who has information on this old town. I know of the Tohichon United Reform Church. This is the land in which my Weisel ancestors built a church whic is no longer standing. They also had a hand in the new church that is still standing and a great number of my ancestors and cousins are buried in this cemetary. I'm looking for information on the town, what it was like befoe the Nockamixon, the creting of the Nockamixon (I have been told it was man made), and any information of the former inhabitants of the town.
