Ken, I know this is old but did you ever get an answer?
Checking my files, George Arlington was the son of Robert Tower and Bertha Hastings.
Checking the notes I found: "Re: Robert Tower born about 1900 Dorchester, Posted by: Nancy Date: March 02, 2000 at 18:21:40 In Reply to: Re: Robert Tower born about 1900 Dorchester, by DerekTowerof 338
Hello: Derek, I am assuming that you are David's, Mike's and Carolyn's brother. If so, I believe that the Robert Tower that married Bertha Hastings that you are concerned about was born earlier that 1900. My uncle, Gordon Arlington Tower was also their son and according to records, he was born in Dorchester on Feb. 8, 1904. There was also Ross, Forester, Ruth, and I believe at least one more daughter - and I am not sure if you mentioned Arnold or not. Hope this might be of some help."
