I focus most my genealogy in Newfoundland and I have seen the Redmond name before, not often as its not common. I scoured everything I could think of and can find NO record of Dennis in St. Johns let alone Newfoundland.
I did find a ships passenger list of a D.J Redmond who was from Newfoundland.
D. J Redmond, age 48. Occupation:Commission
Citizen of Canada Newfoundland
He could read & write
He ported in St. Johns and arrived in New York September 26 1893.
If I can be of help, let me know and I will do what I can to assist
