I don't think this is going to be an easy search...
I found the address for the country club and drove through the neighborhood using google street view. I did come across a house but it was blocked by trees and couldn't get a good view. That place is huge! So many trees!
If you can find the ED# for the country club, that might help. It does appear that the street names have changed from one decade to another.http://stevemorse.org/census/ed2040.php?state=ct&year=19...
Where was James in 1920?
I know Nellie was married to a Harold Neumann ... but that was after 1920. Maybe you could look for Harold's 1920 census record and see if they were in his neighborhood.
Some census sets are "unreadable" but only a few pages appeared to be damaged - not sure if they were indexed on Ancestry - should have checked.
Also checked the WW1 Draft Registration Card for an address.
Have you seen that one? (late 1918)http://search.ancestry.com/iexec/?htx=View&r=an&dbid...
I too have looked for the census record by town only, by given names only, by nationality, YOB.
Not as many Susan's as I thought there could be... but no cigar.
The address that is mentioned on Robert's 1921 passenger list is "Hillcrest, Ridge Road, Whitneyville, CONN."
The difference between the two streets is 1.8 miles.
I will check the Hillcrest Ave. census records and see if anything shows up.
