I wonder if we could work out a Sindarin meaning for Hamilcar? Or at least a plausible way it could be a slightly-modified Sindarin name?
Some Sindarin words that start with H....

Sindarin words starting with 'am-':
#

amarth n. “fate, doom”
amartha- v. “to define, decree, destine”
amdir n. “hope (based on reason), (lit.) looking up”

ammarth
n. “fate, doom” see
amarth
amon n. “hill, mountain with steep sides; lump, clump, mass”
amrûn n. “sunrise, east, (lit.) of the uprising”
Of course, Sindarin has lenition, so an initial 's' sound can undergo mutation to become 'h'. For instance, if you put 'the' in front of them...
#
sam n. “chamber” --> i ham "the chamber"
sammar n. “*neighbor” --> i hammar "the neighbor"
saw
n. "juice" --> i haw "the juice" (apparently this is more like "filth, putrescence" than "fruit juice")
Here are the words I can find with "-car" in them. Of course, being in the second position in a compound, lenition might be expected, changing c -->g. So, it's unlikely that "car" would be a separate element in "Hamilcar"
car- v. “to do, make”
carab n. “hat”
carach n. “jaws, rows of teeth”
caralluin adj. “*red-blue”
caran adj. “red”
caras n. “circular earthwall with dike, fort surrounded by bulwarks; city (built above ground)”
carch n. “tooth, fang”
carfa- v. “to talk, speak, use tongue”
#
carn n. “deed”
#
carth n. “deed”
carweg adj. “active; busy”
"ilcar" isn't a word in Sindarin, I don't think.
-il suf. “feminine suffix”
il adj. “*all”
ilaurui adj. “*daily”
Hmmm...so Hamilcar could maybe mean something like "The room (is) all red"? Halbarad = High tower, so it at least keeps the architectural theme going....
