I recently added a new Brooklyn Genealogy Resources page featuring, among other things, a map of Brooklyn Catholic churches. I created it a number of years ago, to assist in my own research, but I've always hoped it could be useful to other people, too. I've featured it in posts in the past, but thought I'd like to have it more prominently featured and more readily accessible. A number of people have told me they've found it helpful when I've linked to it on mailing lists and elsewhere, so here it is, permanently accessible. I am not the most tech-savvy person, so it had literally never occurred to me that I could embed it, other than in a post, until a couple of weeks ago.

The map currently includes the Brooklyn Catholic churches founded through 1900, though I hope to one day update it to include younger parishes.
Google has unfortunately rather gutted the functionality of this map since I originally created it. It used to be possible to take a custom map like this one, and then search for an address, like the address where you've found your family in census records. That address would then show up on the custom map, surrounded by the markers for the nearest churches. Now that searching for an address brings up that marker on a new map, you have to use two different tabs, or otherwise make sure that you're looking in the right neighborhood, rather than being able to plot the addresses against each other. It's still useful, I think, and I return to it frequently to work on different family lines, so I hope that my readers with Brooklyn roots will find it helpful, too - along with the other resources highlighted on the Brooklyn Genealogy Resources page.
This map was compiled using information from the Local Catholic Church and Family History & Genealogical Guide by Ann Mensch as well as the page Roman Catholic Churches of Brooklyn, N.Y. by Tim Desmond.
