It would appear that we, too, may be able to assist one another in researching this line.
FYI, Lewis (also seen as Louis) and Charles were brothers to George (Jr.) and Sarah. In fact, I show seven children in this generation: Margaret, Sarah, George, Louis, Charles, William and Rufus. Margaret died at the age of seventeen months.
I would like to compare notes with you as well. Please contact me privately if you are interested.
