As I think Azizi has shown (I hope I am not mis-reading), syllables that look like prefixes or suffixes in English or other languages may or may not perform that function in naming, and may or may not have the same meaning even if they do.
I actually knew of a baby named'Devon.' His parents had a friend who named their child (female) DeVonne, and they assumed that Devon vould be a male equivalent. They certainly weren't thinking of either the English Devon or the prefix 'de.'
There are only a very few African-Americans in the province (western Canada); they came here only because of the two professional football teams in the province which contract American players. Most with African origins here are from the Caribbean or Africa; their naming practices follow their particular homeland culture or, if Catholic or C of E, the church's practices.
