Every Monday we will post an entry that hasn’t yet been published with a view towards harnessing the collective onomastic power of the internet. If you have any thoughts about the name’s origin, other variants it might be related to, other examples of its use, etc., please share them in the comments! If you wish to browse other Mystery Monday names, there is an index.
Today we give you not one but two names, because both involve the same prototheme, Rece-. One is from 12th C France, the other from 10th C Spain. Is it the same element in both? Do you know of any other names with this element? Let us know!
