Rose (Springer) O'Connell - McAvoy

OK. So one goal for the New Year was to do more in depth research on my Springer line. I was reading old O'Connell posts today and found a message my aunt put up a few years ago. This message stated that Rose had a sister Sophia. I already know that she had a brother William and her mother was Mary. I searched the 1900 census and found a family in Maine that fits these family members. The one exception is that the Mother is listed as Mosel, I cannot read the original copy to clearly. It looks like it could be Mary instead of Mosel. There is another brother listed as well. His name is Arthur. Will see if I can find them in 1880, 1910 and go from there.
