I am doing some research for my daughter's own genealogy book, and working on my ex's side. His grandparents names were John Petersen b. 1909 in New York. He married Anna B Henning on August 4 1935. He joined the Coast Guard (?) and moved to Panama Canal, he was a tugboat captain,where he had Sue (ex-husband's mom)I am assuming she was born in the year 1957. Any info if this sound familiar would be great! Thank you!
