It just occurred to me.
How do you pronounce @Cecil_Adams first name?
'See-cil’?
Or
'Seh-cil’??
When I’m feeling fancy I say Sehcil
Wonder how Cecil himself pronounces it?
I need to know.
I do not know any IRL Cecils, but in my head I say See-cil
I go with See-sil myself.
Like See-Sill, just like Beany and Cecil
I know one Cecil and he says it like “see sill”.
I never even realized there was any other way to pronounce Cecil.
I’d say SEE-sill. And, yes, like in Beany and Cecil. 
SESS-sill sounds fancy, like Cecil B. DeMille.
Sea anemones are sessile.
Same here. But what about Cecilia? You don’t pronounce that “See-selia”, right?
I’m British so always read it “Sess-ill”, even though I know that Zotti and most of the US pronounce it See-sill. I normally adapt the pronunciation of things to fit people, but See-sill just sounds ugly and wrong.
A friend of my wife has a grandson named Cecil. I always call him Seh-cil. At 4 years old, he gets a kick out of his extra fancy pronunciation.
Very much this. I would sound ridiculous saying ‘see-sil’, and would treat anyone who did with deep suspicion. Unless they were American.
I had an uncle named Cecil - we pronounced it See-sul, stress on the first syllable.
He was a trip! Always getting us and himself into trouble. 
RIP, Uncle Cecil.
seh-cil, like cecilia.
I say suh-SEEL-ya. Like Simon and Garfunkel. (I’m from Texas, by the way.)
a very good song.
I pronounce it Ed.
I was waiting to hear from a Brit. I will now pronounce it Sess-ill forevermore.
Hear His Name uttered:
These.
