[Thamesite2017]

Is anyone researching the Melvin family and a
ALEXANDER MARK MELVIN born 1824 Canada

1851 UK census
Name: Alexander Mark Melvin
Age: 27
Estimated Birth Year: abt 1824
Relation: Visitor
Gender: M (Male)
Where born: West Canada, Kington
 
Civil parish: Hampstead
County/Island: Middlesex
Country: England

trying to tie this up with a Alexander Melvin who dies 1888 Thames New Zealand
which states he was native of Canada

Can't find any other mentions for a birth
there are several Melvin families in nearby Auckland NZ, so whether he is related??
