Hi Richard
Looks like it could well be your Hilda as I have found a George Shaw in the SSDI, who died in June 1981, whose last residence was Suffolk County also. His birth date is shown as 4th May 1885 which is the same as the George Shaw found in the WWI draft index cards:
WWI Draft Registration
George Frederick Shaw, 149 Engert Ave, Brooklyn, NY, age 33 born May 4th 1885, England
Occupation, Motorman, B.R.T. Crosstown Depot, Greenpoint
Nearest relative, John Shaw 152 Mecker? Ave, Brooklyn, NY
Medium height, medium weight, brown eyes and brown hair
Date of registration, September 12 1918
I do believe that we are getting there

Yes, I did see the George Frey marriage of 1910 and had hoped that the births of Reginald and Magdalena would have been solved with an earlier marriage. Never the less, George and Maria were certainly not too old to have had these children in their forties

I see that you have located the Lehmann's! Good work

I presume that you have decided to take up the world subscription....you won't regret it, I know that it is quite expensive but I certainly wouldn't be without it

I will have a look for them and see if I can help with locating any more info
Best wishes
Agnes
