I don't have any of the info you need.I came across this site by accident.My Grandfather was Joseph Walker Derum Sr. My father was Joseph Walker Derum Jr.I met Pauline when I was a child.I believe she was my great aunt.I believe you may be my 4th cousin. My dad used to speak of someone named Mooney or Moodey, I'm not sure which.I never knew my grandfather. He may have died before I was born. I don't know. I would love to have a picture of him.I hope I'll hear from you. I think I may be a generation older than you.
