Elias Olsen

Hello forumites - I have two small bits of information regarding my father. Firstly, someone asked whether he had ever worked on ships and I do remember my mother speaking of him working on ships. Also, my sister's middle name is Madeline/Madeleine because this was the name of Elias's sister. Finally, I know his grave site says 1900, but that is incorrect and when the gravestone was finally done, my mother's mind had started to slip. His birthday could be any time, I only said July 2nd as I was tracking the wrong Elias.
