Hi Janet,
Re the 1899 death for a Janet Summers on the NSW BDM online.
The information on the index shows that particular person’s father’s given name as unknown Campbell and that the death occurred at North Sydney and was registered at the NSW BDM offices for the St Leonards district. (#10845)
The information on a d.c. is only as reliable as the informant’s on knowledge, and it has not been checked by the NSW BDM for its accuracy. The index could be for someone else other than your George Summer’s mother. A transcript of that d.c. would provide you with the details for the informant, and it would also provide you with that particular Janet Summers then age, any marriage/s, the names and ages of any children of those marriages, her usual residence, cause of death, and the burial details ... funeral director, clergy, cemetery etc.
Perhaps the most significant piece of information if that would be for your George’s mother, would be the number of years in the colonies, as often it shows how many years in each separate colony.
Re Immigration to the Antipodes
Do you have any evidence to suggest that George’s parents came to any of the colonies?
Have you considered if George or any of his immediate family may have come via New Zealand, or may have used the surnames Summers, Young or Henderson?
I ask because:
When I was transcribing the census information for you I noticed on the 1851 census that George’s mother’s surname was recorded as Henderson.
I also noticed that David Summers was not there, and that a 20 year old was the Master Baker with 2 employees.
To my way of thinking, as David Summers was the Baker in 1841, and then his step-son becomes the Baker in 1851 and David is not present, that may well indicate that David had died rather than immigrated. The Scottish census was taken 30/31 March 1851.
If David and Janet came to Australia, perhaps David came before her, and then sent for her, perhaps the marriage failed and David and George came to the colonies. Perhaps Janet remained in Scotland and reverted to Henderson, which would be her maiden surname.
So perhaps there’s later Scottish census for the Janet Henderson that would be for your George’s mother. So perhaps there’s Scottish death registrations for George’s mother and father.
However, speculations are simply that. Primary Records provide the paperwork trail, and as I am not familiar with researching Scottish primary records, , I hope you make contact with the submitter mentioned on the Australian Royalty family history link I gave earlier. They seem to have quite a deal of information, perhaps they have good understanding of the various UK paperwork trails. They may even have researched information to share directly with you.
If you do decide to follow up on that NSW 1899 death registration for Janet Summers, may I suggest you look at ordering a transcript from an official transcription agent. These are cheaper and quicker and can arrive in your email inbox as an attachment, eg pdf file...
Cheers, JM
