Hebrew > English: Last name "מאלב"

Per family lore, my great grandmother's maiden name was reportedly "Maloff". She lived in Nesvizh, a town near Minsk during the period 1871-1923. The only documentary evidence I could find of her maiden name was "Mollef", from a listing in the 1911 New York City marriage index of her daughter (my grandmother).

I have not been able to find any other official documentation listing the great grandmother.

Recently, I found a genealogy tree listing for a different ancestor with the maiden name מאלב. The tree shows the English transliteration of that name as "Malev". That ancestor was born in Nesvizh in 1810.

I am interested in learning whether or not מאלב and "Maloff/Mollef" are possibly different versions of the same last name.
