Okay....this is a big longshot, but one never knows. ..... And I have to ask the question Eric, is it possible that you are of Chinese heritage?
Hi Deb, that is an amazing find. My wife thinks it isn't possible, because that would make me one-eighth Chinese and my mother one quarter, but there is no evidence of any of the characteristic Chinese features such as straight black hair - most of my relatives in this line have brown wavy to curly hair.
But I am not so sure. Possibilities include:
1. The original Mr Ah Sing may have already only had one Chinese ancestor (say a grandfather), so my genetic inheritance would have been far less Chinese.
2. I'm intrigued by the marriage to Mr Mardgraves (presumably a mis-spelling) in 1874, and the birth of children surnamed Ah Sing in the period 1882-1892. I have heard of cases (there is one I found in my wife's family line) where a woman had children by several different fathers, some named, some unnamed, and there being some uncertainty about which of several men were the father in some cases. The final surname can reflect current partnership rather than the actual biological father. I think it may also be possible that some births are registered long after the actual birth.
So could it be possible that Mr "Mardgraves" was the biological father but the births were registered under Mr Ah Sing?
This leads me to a few other questions please ....
1. Why were these children on the state wards registers if they had mother and father? Had the parents died or split??
2. Was the date of George Henry's birth in the BMD register also 1888? Could the birth have been earlier than the registration?
3. Did you check any of his siblings' births in the Aust Birth Index? (If not I will do that when I can get to the library.) I would guess that birth dates in a state wards register might be less reliable.
4. I wonder whether Mr "Mardgraves" had any children in the birth index. Again I will check.
As you say, it's a big long shot, but I don't have any easy shots left, so it is definitely worth looking at further. I think it is doubtful I have Chinese heritage, but I think it would be rather fun if I did. Thanks a lot for your amazing detective work.
