With there being two Isabella Andersons connected to Francis Snr, we have to consider that either one could be the mother of Maggie Ann. It could have been daughter who came home to have baby or Isabella who married Francis who was already with him at the time of Maggie Ann's conception and birth at the beginning of October 1859...
I've had a look at Francis Anderson and Isabella Anderson's marriage cert to compare the signature of Isabella to the Isabella on Maggie Ann's birth cert. Both are just 'her mark'. So from this I feel that the 'wife' Isabella daughter of Robert Anderson and Elizabeth Ferrier is Maggie Ann's mother.
Question remains though why is the father's name blank on this, even if Maggie was illegitimate? They married only 2 months later.

I suppose the father is someone else, and she was just told that Francis is her father, even if he wasn't, hence him popping up on Maggie Ann's marriage and death certs.
Haven't got access to A/try at the moment, just a free account.
Thanks once again.
Edit: Just had a thought pop into my head again. My great-grandmother was Helen Margaret
M(a)cqueen Anderson. I've not found any reference to a 'M(a)cqueen' anywhere. Having said that it could be a non-relation with this name. Just found it a bit strange.
Have to say the family tree I'm making for this branch is a complete dog's dinner at the moment.
