I live in Lviv - providing genealogy researches and genealogy tours in western Ukraine. Was to Brody great number of times, also did some corresponding researches (but of Jewish ancestry mainly). Now am busy with other researches - but would you be interested - may check catalogues of Lviv archives - for availability of roman-catholic and greek-catholic metrical books (btw - do you know - which church your relatives belonged to?). If interested in research - may contact me by e-mail:
