Looking for information on Gerull from Memel, Prussia, Germany in the late 1800's. My grandfather was Hans John August Gerull b. Nov. 14, 1895 in I believe Memel. His mother was Marie Meier and his father was Frederick or Frederich Gerull. He had 2 brothers one of which I believe was named after the father and one who went missing in WWI. I believe his brother Frederick had 2 girls.
