"LAY-uf-win" or "LEF-win" -- but that's just a stab in the dark.
It's interesting that all three responses so far have the second syllable as "win" and not "ween" / "wine" or "veen" / "vine," or even as two separate syllables, "WIN-eh," etc.
I do like it because I'm drawn to almost any obscure medieval name. But not knowing how to pronounce it is a big setback. :-/ I wish we had a scholar of medieval names in the ranks. At least we might know how it pronounced among professionals, even if we may never know how it was pronounced when originally used. I find that sort of thing fascinating.
