I met a lady (about 70 yo) the other day and her name was Ettaline. I only saw her name written down, so I'm not sure how it was pronounced. Presumably Etta - line, like Caroline. But maybe Etta -leen or even Etta - Lyn? Its pretty written down but maybe not so great when pronounced.
I love names (hence I hang out here a lot) and it made me think of you lot, as it is looks like it is a bit of a hybrid/made up name which is always thought of a modern thing, but this lady being 70ish it seems to have happened in the past too.
Not sure of the point of this post , just general musing.
