Myfanwy *in no way* looks like "my fanny," nor is "wy" on the end reminiscent of urine. I think the people who see that probably easily misread and misspell words that are somewhat uncommon. My name is "Mara" and a lot of people read it as "Maria," and I'm sure to them, "it looks just like Maria!" I think Myfanwy is a strong and lovely name.
In 1964 I went to school with Myfanwy, whose family were recent immigrants from Wales. Her family ensured that we knew that the correct pronunciation was "mu VAN OI ", primarily as she was called My Fanny at school. I got away with "m VAN OH" which eventually degenerated to "VAN OH".
The correct pronunciation of the Welsh name Myfanawy is Muh-van-oi. Any first language Welsh speaker will know that in annwyl, wy and hwyl, the wy is pronounced as the English oi as in oil. So it is in Myfanwy. Miv-an-wee is the English mispronunciation. Dylan is another mispronounced name. The y should be pronounced as 'u' as in umbrella not 'i' as in pit.
I don't know why people are explaining that Myffanwy must be pronounced with a V as it is a double f - the entry for this name clearly shows it spelled with a single f.

In the Welsh language a single f is pronounced as a v not an f. The whole name is roughly pronounced as Mi-Van-We.
