Oh, well. Thanks for checking. It was S E Street - I remember looking it up on an old map on the internet from an archives of maps a while back. I was hoping I could find it with Google Earth, but nothing there, either. Probably went away in the development over the years.
I appreciate your interest/help. Like I said, I was sorta looking for the child, if there was one. Maybe I can find an obit on him that lists his children - if that was him in Los Angeles. I should probably check, just for the heck of it, to see if there are records of my grandmother reapplying for citizenship. If my grandfather even knew that her ex was not a US citizen, he would have known the law (he just graduated from law school the year they married) and might have had her apply.
