I believe I also have information on this line. My ancestor, George Aukerman, married Margaret Gallagher. She was the daughter of Daniel and Elisabeth (Bonebrake/Beinbrecht) Gallagher. I know they lived for a time in Jenner Twp, Somerset County, PA. Daniel is buried there. In addition to Margaret, their children were William, Mary, and Sarah. After Daniel's death, Elisabeth, Mary, and Sarah lived with Margaret and George Aukerman in Unity Twp and Latrobe, Westmoreland Co., PA.
Do you believe this may be the same Daniel Gallagher that you have? If so, I didn't know Daniel and Elisabeth Gallagher had a daughter named Eleanor. Do you have more info. on her? Thanks!
