First an attempt to try to clarify the problem:
Writing for an Eb instrument means you write a C when you want to hear an
Eb.
That's the definition of how pitched instruments are named: when the
instrument plays a written C, the sounding note is the name of the
instrument.
A Bb trumpet playing a written C sounds like a Bb.
A horn in F playing a written C sounds like an F.
An alto flute in G playing a written C sounds like a G.
A horn in Eb playing a written C sounds like an Eb.
So, assuming that is what this existing part for Eb horn is, when the part
writes a C, the sounding pitch is an Eb.
The note you would write for an instrument in F to play a sounding Eb is
the note a 5th above Eb, or Bb.
This means that a written C in the original part for Eb horn would be
written for horn in F as a Bb.
So, everything goes down a whole step, including the key signature, from F
to Eb, or one flat to three flats.
In your case, it is easiest to just transpose the entire staffgroup
%}
sgFrenchHorn = \new StaffGroup \transpose f ees <<
\new Staff \with {
instrumentName = \markup { \column { \line { French Horn F} \line {"I &
II"} } }
shortInstrumentName = \markup \teeny { \column { \line {"fhorn"} \line
{"I,II"} } }
}
\frhornInIINotes
\new Staff \with {
instrumentName = \markup { \column { \line { French Horn F} \line {"III
& IV"} } }
shortInstrumentName = \markup \teeny { \column { \line {"fhorn"} \line
{"III,IV"} } }
}
\frhornIIInIVNotes

\score {
