History & Origin
Marylu is a compound first name written as one word, a spelling of Mary Lou and, behind it, Mary Louise. It joins Mary ('beloved', 'star of the sea') with Lou, from Louise, 'famous warrior'. Fused Mary- names like this were a fond mid-century American, and especially Southern, tradition.
It was never common in this joined form, borne by only a couple dozen girls a year around its high near 1953. It reads as a warm, homey double name of that generation.
