Mervyn is the anglicized form of Merfyn, a Welsh male name of uncertain meaning though several possible meanings attributed to it are:
- “marrow famous” from Welsh mer (marrow) and myn (eminent);
- the first element of the name could also possibly be derived from Welsh mawr meaning “large; big; great”;
- it’s also possible that Mervyn is a variant of Myrddin which is the original Welsh form of Merlin; it means “sea fortress” from Proto-Celtic *mori- (sea) derived from a PIE root; and Welsh din (stronghold, fortress) from Proto-Celtic *dūnom which is also derived from a PIE root.
Mervyn is also a Welsh surname derived from the given name.
