I recently received a family tree sketched out by my great uncle. He noted that my great aunt's father's brother was a "cabin boy" and went down on the Titanic. He's noted as a sibling of Albert, William, Harry, Charles and possibly others. This seems to match somewhat with this listing for Augustus George. The spelling I have however is Standbrook. I'm wondering if this is a match or not ; it's certainly the only close match on surnames in the list you have. Any insights appreciated.
