Hi Jeff,

FamilySearch has NYC death certs transcribed (not all info from cert) but enough to help you identify if it is the correct person.

I found three men named George Lawrence who passed on in Manhattan during the 1930 through 1940 timeframe.  I did not search all five boro's, but you should do that.

Hope this helps,
