Your going to have to look in the other switches and start doing some drawings.
With the information you’ve given it would be pure guesswork on our part.

Hi ,brown,black,grey are the strapers for two way switch.the only way to identify the switch wires is to connect line and cpc to the ceiling rose and test for continuity on the switch but only after safe isolating the circuit,if you have continuity then they are the switch line and the brown is the switch feed .
good lack
