It figures. Now I can't find the census or my note that I wrote it on. It would be somewhere in the vicinity of Littlestown. Historian John T. Reiley mentioned it when he wrote about where some families lived in Adams Co., but all he said was Flatbush. I found it mentioned in one of the Gettysburg historical newspapers but, again, it just says Flatbush - as if nobody needed to ask.
There is a family in my extended tree who were reported to live in, or near Flatbush. Later, in the wife's obituary, it said that she was a lifelong resident of Union Twp. In the 1880 census, her husband's occupation was a "lime burner." I hope that is enough clues to connect the dots. Thanks!
