Hi Ellen: Thanks for your answer. That is exactly what I am finding. I have had a number of cases where my French Canadian families' names were seriously mangled in various census records so no amount of searching would ever find them. However, I am finding some census records for them and noting that their address stayed the same for many years, I was wondering how do could I find the ED numbers. I just Yahoo'd it, (I don't care for Google), searched for, "United States Census ED finder" and up popped the Stephen Morse site. I had used his Castle Garden site for many years and had no idea he done this for the census records. I find it pretty amazing. If you play around with it, sometimes you get multiple ED's, but clicking on one brings up a spreadsheet of the ED's versus different streets. At worst, I had to browse two ED's, but less than 40 images each, so pretty quick. Cheers, Jim
