Yes, Isembard from Drambuie. (Isambard is the Brunel spelling, but I'd used that clue once before - sounds like a Tookish engineer, or something).
The sheep bit is 'ewe' because it sounds like U. I did start with 'yew,' but reading that the yew tree is highly poisonous, I didn't want to mention it in the same sentence as a drink (yes, I'm weird).
I probably indicated the S by saying add direction - I can't see my clues on my phone at this point without a lot of scrolling.
Well done both, and over to Galadriel!
