South Australian look up ROGERS/SANFORD

[carol8353]

I have found an ancestor who had three children in Sydney.
Mary Sanford born 1859
Sarah A Sanford born 1862
George H Sanford born 1863.

The girls and mum Anne(ie) Sanford nee Rogers were back in London in 1861 with grandma.and in 1871 just the girls were here.
From looking at the NSW reg of BMD I found that dad was Henry Sanford.

But I have been unable to trace a marriage for the parents or any sightings of either of them after Anne was here in 1861.

I've tried looking up marriages and deaths on the NSW site but found none that could fit my family.Do you have access to any other records that could help?

Many thanks in advance of you finding some info for me 

All the best

Carol

PS Anne Rogers was born in Marylebone in 1837
