Help please- tracking a birth certificate

[Sanddancing]

I am currently trying to track down Scottish DH’s paternal grandmother. We know her Irish parents were married in Ireland ( found the marriage certificate) and most of her older brothers and sisters are born in Ireland, although they seem to move about as a family.

By the 1901 census the we know the family are in Scotland and that grandma is born in 1896 ( dates match granny’s wedding certificate, marriage is in Scotland in 1914).
There is an:older sister with a Scottish birth certificate born 1891, but no birth certificate for granny in either Ireland or Scotland that I can see-
any thoughts about where it could be?
DH’s granny is the youngest child born to her Mum and Dad that I can see ( from the 1901 census).
I’ve used ancestry, Scotland’s people and https://www.irishgenealogy.ie to get this far.

Maybe her birth simply wasn't registered? Or her parents named her something and then referred to her as something else? (People did this. My aunt was registered/christened by one name and then called a completely different dissimilar name for the rest of her life. God knows why.)

Maybe, the other, older children were registered in Ireland or Scotland, and the name she is known by is on her marriage and death certificate.

i did wonder if none registration was a thing, something to think about, thank you

Edited: sorry, I was going g to suggest Scotland's People then realised you'd already tried that. Have

How close to the Scottish border were they living? Is it a possibility that they were in England at the time of her birth?

If the family moved about a lot, it's possible (if not very probable) that they might have emigrated and then returned. I've wasted time looking for someone all over the Irish and British records and then learned that they were actually born in Australia!

Agree about the name thing. My grandmother was Alice. At her funeral the vicar kept referring to Dorothy. I was very confused. She was actually Dorothy Alice but had never been called Dorothy. The vicar obviously didn’t know her at all!

What did the Census say about her place of birth?

I'm sure you may have done this already, but it's possible to search the Irish Genealogy records using just the year & surname, and checking each entry to see if there's another unknown forename. If you know the year of birth it shouldn't be too bad (December babies can sometimes be on the next year's records). I just hope for your sake it's not Reilly or Murphy. Or could your DH's grandmother be adopted/a foster child? Does the 1901 census include the 'number of children born' to the couple?

The 1901 Scottish Census does not include that. It's the 1911.

If all the other children are registered then she is likely to be too - maybe a transcription error so try some spelling differences?

Also maybe a different forename - I've one in my tree born as Agnes, marrying as Nancy and dying as Elizabeth Agnes - are there any of them that could be possibles?

Also maybe try just the surname and Mother's maiden name to see if that throws any possibles up.

I watched an interview with Billy Connolly the other day where he had a very similar situation involving his grandmother. It turned out the great grandfather had been a soldier and the girl had been born in India.

I've seen an 'Eliza' turn into an 'Elisa' on the census and then 'Elsie' on a marriage register.🙄
Also Irish census database isn't very good at detecting name variations - an 'h' left off Sarah meant name was not picked up. She was there, just had to use a roundabout way to find her.

Are the family in the same area on the 1891 birth cert and the 1901 census?

Might it be worth looking fr a baptism instead?

If they moved from Ireland to Scotland, it might be worth trying to find out when that happened by looking at passenger lists of vessels. Can't remember how to locate such things, but I think some of the online resources such as Ancestry and Genes Reunited have passenger lists.

Finding out when (and where) they arrived in Scotland could make it easier to trace the birth record. Also bear in mind that Irish and Scottish accents are different, so there could have been confusion over spelling. I've had that issue with Cockney ancestors!

There are no passenger lists between Ireland and Scotland available.
