Hi Tina,
It's good to see that you are researching your Irish ancestry. Although I'm not aware of Quarry Cottages, Crumlin suggests that it's in south County Dublin. As such, it might be a good idea to focus your efforts there.
As you're unsure of the surname and possibly the dates your ancestors lived in the area, I would recommend that you check out this page about the
County Library, Tallaght on the South Dublin County Council website. They may be able to help understand whether or not, whether now or in the past, there was a Quarry Cottages in Crumlin.
I think that's a good starting point.
Regards,
Eoin
