I thought of Blanche, Gail, and Lane. Also, if Steph is accepted, why not my cousin Les (short for Leslie)? I have no idea how a person would go about collecting all these names. Sounds like a huge challenge!
It was a huge challenge, and still is apparently :) I added all your names except Gail, which I think is two syllables: GAY-ull. If Gail is accepted, then Dale, Gale, and Dail would have to be as well...
Well they wouldn't as Dail isn't a forename and Gale is misspelt. You did miss Sian (pronounced Shaan for those heathens who think it's pronounced Sigh-Ann)
