Paula Abdul!
What do I win!?!
Huh!
Kudos!
Oh you win big, alright. You’ll have to double-work for it, though: https://www.google.ca/search?q=skittles&client=firefox-b&dcr=0&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjjosXE5avZAhUB5mMKHdZDBeMQ_AUICigB&biw=1029&bih=802
Sure, I could be a total nurl and contend that technically there’s an “uh” sound at the end of Paula, which doesn’t quite match up with the short vowel “a” sound beginning Abdul, however, in my venerable, fusty senescence I’ve come to roll with those punches with a veritable Red Buttons-like homespun charisma.
And warmth.

Excellent “y” connection! (as I’m now realising that a ‘y’ connection will be a near-impossible phonetic one, given that the long ‘e’ vowel ending of Maury doesn’t meld with the consonontal ‘y’ beginning of Yeston.)
Also I’d consider the name Maury Yeston obscure enough (along with Prof. Pep’s Barbara Acklin) to warrant an accompanying livlihood descriptor.
thanks!
Oh I’ll really enjoy this one…
