My maternal grandmother's origins

[Joby86]

She may not even be named SMITH which is yet another thing that confuses me lol

[Ladyhawk]

Lander was her married name yes, before that/from 1936 she was Palmer but prior to that is the question. She always had the name LOUISA BRASSINGTON SMITH as who she suspected her birth mother was but where she got that from I sadly do not know. My wife seems to think that she was in fact a blood relative to her adoptive mother but again I have no idea how factual that is.

Don’t know if this person is of interest

How do I find out if she had a daughter in 1934?

[CaroleW]

There are only 2 ways - DNA or apply for her full adoption records.  See link posted by Pauline in reply 2

If your mother or one of her siblings is still alive - it's probably best one if them apply as a direct first line descendant

[Joby86]

My mother is alive yes and DNA is a plan yes. Thank you all SO much for your responses and advice x

[CaroleW]

Louisa is on the 1939 register and there is one redacted entry indicating there was a child who may still be alive

However - it's uncertain if Louisa is the right person so it's best to go down the DNA or adoption records route & establish the facts first

[CaroleW]

There is a Louisa Brassington Smith tree on Ancestry but it shows no known children in relation to her marriage

[Joby86]

There is a woman by the name of, Annie Palmer Collett (known as Nellie) who was the sister of my grandmother's adoptive mother, Dora Mercy Collet and there is some possibility that she was the mother and Dora and Thomas Wilson Palmer (who she married) adopted my grandmother

[CaroleW]

There is a Collett/Collett birth on freebmd in the March qtr 1934 you may want to bear in mind.    There doesn't appear to be any trace of her after that entry.  No marriage & no death.

However - her mother may have married & she took her stepfathers surname or - she also may have been adopted

Too much speculation can lead you down completely the wrong path so you need to start with the basics - DNA or applying for her full adoption file
