I am stuck at the 1790-early 1800 period. I have documentation back to Obed Chamberlin (b. abt 1790, d. abt 1830?). I am unable to connect him to a father/mother. There were several Chamberlin/Chamberlain families in the area, which is on the border of Chester and Lancaster counties in PA, as the fourth gemeration was coming along. They descended from Jonas Chamberlin, were Quakers and the first three generations are very well documented. The turn of the century saw a lot of accusations and disownments within the Quakers. One Chamberlin was accused and apparently was eventually cleared and accepted back into the Friends, but then the whole family appears to have quit attending and they were disowned for that. (They may ahve became Presbyrterians, but I am looking for proof of that as well) Once they were disowned there are no more church records. I find one census record of Obed in West Fallowfield Twp. (neighboring Twp to the S.) in 1830 and I found that he served in the War of 1812. He seems to disappear (I assume died shortly after 1830), but there were a wife (widow) and two sons and two daughters. Obed had three brothers; George (b. 1795) who married Elizabeth Slokom and moved his family to Redford, Wayne County, MI in the 1840's. William Marsh Chamberlin (b. 1809, d. 8 mo., 1879) married Rachael (Pennington?) (b.1813, d. 1893) was a prominent farmer in the area around Sadsbury (Christianna, PA). Both are buried at the Sadsbury Friends Cemetary. Thomas Chamberlin who apparently served in the Military and was on pension in Salisbury Twp (neighboring to the N.) in the 1870's With the Military connections it appears that some had broken completely with the Quakers. Any information on the parents or any other siblings will be greatly appreciated. I also have considerable information on the earliest three generations that I can share.
