English pet name for Rose or Rosa, from Latin "rose", and for other variants and derivatives of those names (see above). In the last century Rosie has become a popular given name, especially in the US.

Note: Although ONC states that it was first used in the 1860s, there are several spelling variations of Rosie in the 1841 Census of Aberdeenshire. All are very rare and should be found with Soundex searching.
