I don't know if we have a link or just similar names in our families but I will post this in hope that at some time it will lead somewhere.I have hit a wall with my Foulkes family research.
My great grandfather was Peter Ellis Foulkes born in Liverpool 25 Sept 1850, married Sarah Bonny on 6 Apr 1875, had 2 children who survived him, Thomas and Jessie. Peter died 19 Aug 1887 while a crew member on an English ship at Port Limon, Costa Rica. Their two children that died young were David and Sarah Elizabeth.
I have a journal that Peter kept during various voyages.He writes about shipping out of a port in California using the name Thomas Ellis. Also in the journal is an address "Direct to Emme Ellis to the Care of Mrs. Ellis, Berrella Street Wollongong is fifty miles from Sydney New South Wales."
