I have a lot of Phebus/Phoebus data, much of which was transcribed from a book put together by one of my ex-husband's relatives. Unfortunately, I was new to all of this and didn't cite the original sources of the entries. And I no longer have the book in my possession. I have a George born Abt 1790 (see below) and marrying Rachel Henderson in Ohio in 1817, though I don't have daughter for them. (But this would make Nancy Phebus his aunt as you suspected, so that fits.) If you could pass along any other info you have on George and his descendants, I would appreciate it!
