Marigold f
English: one of the older of the group of names that were adopted from words for flowers in the late 19th and early 20th centuries. The Old English name of the flower was golde, presumably from gold (the precious metal), in reference to its colour. At some time before the 14th century the flower became associated with the Virgin Mary, and its name was extended accordingly to marigold. Not until the 19th century was this used as a female given name.
