Hi there,
Welcome to RootsChat.
I wonder why you are asking about Walgett?
I see from the online NSW BDM index that Margaret F DAVIS married William A MARTIN and the marriage was registered at Sydney (as in the head office district ie the CBD of the City of Sydney).
From the marriage certificate, what information does Margaret give about herself and also about her parents …. For example, where was Margaret born, what was her age at marriage, what was her usual address, what was her father’s occupation?
Here’s some information from the 1902-3 NSW Electoral Roll for the electorate of Gwydir. I have looked at my hardcopy of two of the polling places in that electorate. Davis is a very popular surname, so it is possible that the chap at the Walgett cemetery is not connected with your Margaret, and perhaps we need to search further for you. If George was noted as a carrier/teamster/drover/shearer then he may have regularly travelled some of the Travelling Stock Routes from Central Queensland down through to Walgett and then down through to regional Victoria or South Australia. While that is quite a large geographical area, it was (and still is) sparsely populated, so while it may take a bit longer to find him, there may well be extant records that name Margaret as his daughter. And that would ‘clinch’ your research of course.
