Mother's maiden name?

The tree mentions Uniondale, but this place is rather far from Prince Alfred, so I'm a bit suspicious regarding the location.

Update: This is that 1882 baptism: https://www.familysearch.org/ark:/61903/3:1:S3HT-65G9-DT3

My mistake Treespirit. I agree it is a long way away. Though if the tree is found to be correct (what a pity there are no sources!) then the siblings are born in various locations. I'd like to find the father Daniel's death/probate, which may solve a few mysteries. Looking...

Update: Thanks for the christening link. I note the spelling variant of Oosthuysen

It is the estate files that you'd want for the parents as they mention the children. I've had a try but haven't found them yet.

Thank you Wivenhoe, yes I have the same information. The witness on the marriage cert was also the witness on another marriage cert on the same day, which makes me think she might have been a "ring in" for want of a better expression.
