Hi Darlene:
Just about the time you think you have it figured out, someone throws you a curve. :-)
My father John Bull, jr. was born in Washington D.C., 1895.
His father's name was John Bull. I don't know where my grandfather was born. Could this be a part of your line? I can't remember my father talking about a sister, but I didn't know my father that well. If it sounds like we connect, please let me know.
Best regards and keep looking,
John
