The ending VILLE in Roseville is suspiciou. Ville is of French/Roman origin. Nearly all Irish town names have Celtic roots. Of course, when your ancestors orally passed your genealogical info from one generation to the next, I can see how Rosenallis could easily be mangled into Roseville.
The Lawlor surname seems to occur predominantly in Co. Laois. You are likely looking in the right church, just the wrong pew. Hopefully more rcds will be found, transcribed and entered in the database(s). I have read many annecdotal accounts where a poster state he/she has gotten records directly from the parish, but these aren't in the IFHF database (yet).
