I am not researching Taits, but I do have many roots in Williamstown, Dauphin Co. I would be happy to check the census index for any Taits, if you like. I have access to the PA census, as I work at the State Library in PA, but would have to check on my lunch hour. I won't have time this week and will be away on vacation next week and will unsubscribe from the list for that time period. Let me know if you have already checked all the PA census. There is also a historical society inWilliamstown. It's small and I rather doubt they can do any checking for you as they are only open on Mondays 10-2-but who knows. Their number is 717-647-9220. My e-mail at work is kchila@state.pa.us.
