Thank you for taking the time to look. Perhaps his surname was Boyd? Middle name Thompson.
It is possible also that he may have changed his name.
I have read articles from Melbourne stating that he was American, from Philadelphia, yet on a ship manifest from 1915 he gave his details as Scottish, born in Glascow.
Edgar's grandson (also Edgar) married Elsie in 1942.
I'm unable to find any documentation of his parents names, although in 1896 an Amy Thompson Boyd died in Victoria, aged 52 (making her approximately 20 years older). Edgar put an article in the paper at this time thanking people for their recent cards and flowers during his recent bereavement.
He married Elizabeth Ann Ogg the same year.
Thanks again, your time is appreciated
