FYI -- Right now, I'm using the digitized 1940 NYC telephone directories hosted by the NYPL (<http://directme.nypl.org/>) as a clue for addresses where my husband's ancestors and other relatives may have been living during the 1940 census enumeration. I'm also using Ancestry.com's WWII Draft Registration Cards dated 1942. [Unfortunately, I can only identify his two Brooklyn-based grandfathers in the WWII old man's draft cards; one isn't listed in the digitized phone book at all, and the other's name is so common that I don't know which of the 6 listings might be him.] Anyways, I'm then using Steve Morse's unified 1940 census ED finder (<http://www.stevemorse.org/census/unified.html>) to search on the addresses that I find in the directory listings or the draft registration cards. Then I look at the address on Google Maps via Steve's link to that to try and determine how to narrow down the choices when looking for a street that is covered by lots of EDs. One ED I was looking for was for 522 Ocean Avenue in Brooklyn, where I hope to find Theodore/Pat Israel and his wife Anne (Taffet) Israel. Of the 4 ED's that Steve's tool showed me, I found that address in the last one. So I thought I would save anybody else also looking for 522 Ocean Avenue the trouble of searching through all 4 ED's that came up when I selected Church Ave as the cross street -- you'll find 522 Ocean Avenue in ED 24-2503B. I'll share other specific EDs as I identify them. -- Mary
