"Form of Rosemary"
The name Rosmery is commonly a female name from the "Latin" origin.
Rosmery is a respelling of Rosemary in which the second element is written -ery rather than -ary, with no change of meaning; the two spellings are pronounced the same in English. The spelling first appears in United States birth records in 1988, which is consistent with a form introduced to the records rather than inherited from earlier English usage.
Rosemary means "Bitter rose".
The pronunciation of Rosmery is roz-MER-ee.
