I'd pick something off her registry, and/or make something personal.
I made my brother and SIL a quilt for her shower.
Other ideas: Framed wedding invitation, double panel frame of bride and groom baby pictures, mongrammed cotton blanket, plaque with Irish Blessing (or other culturally relevant blessing/toast), Ask around, maybe you can get their cake knife (engraved), ceremony candle, guest book, cake topper or toasting glasses.
