Who were Sarah Maynard's parents?
 

Does anyone have any record of Mary, born about 1770 in or near Bermondsey, Kent?
She married Thomas Maynard of Bermondsey (button maker) and had at least one daughter, Sarah, born 1789.
Sarah married John Pelham Crookenden of Rotherhithe in 1817.
I would like to know what Mary's maiden name was.

There is / was no Bermondsey in Kent as far as I know. Do you mean the Bermondsey which was historically in Surrey and is now in London? Since you mention Rotherhithe I would assume so.

Sarah Maynard's baptism record? :

St Olave, Bermondsey, Southwark
Christenings November 1797
Sarah D of Thomas & Mary Hayward Button Maker B[orn] October 16, [baptised November] 12.

It definitely says Hayward on the image but Ancestry have transcribed it as Maynard. But because you say the father's occupation is button maker, it seems to fit despite the year being wrong? Of course it could easily have been written down wrong on the register as it was likely copied from another document.

Sarah Crookenden's death was registered Jul-Sep 1872 St Olave, with her age given as 83, which would fit better with her being born in 1797 than in 1789. If that is the right death record, of course! I will see if I can find her on the censuses to see what her age is on those.

Okay, on the 1841 census Sarah is down as age 50 (i.e. 50-54) and born in Surrey:

Her husband died in 1847, so she should be a widow on the later censuses if that was the right death for her.

This could possibly be her in 1851?

Thankful Bookenden Head Widower 89 Retired Ship Builder Kent Brompton
Sarah Crookenden Niece Widow 61 House Keeper Kent Witersham.

Surely his surname can't be Bookenden? But it does look like it.

Hello 'Kiterunner'
Thank you for helping!
Sarah Maynard was born in 1789 from the record images I have seen on Ancestry Uk, though I will check again.
You are right, Bermonsey is in Surrey, not Kent!
As for the surname being different - I will also check the images of documents I saved on Ancestry - but I am practically certain that it was a Sarah Maynard who married John Pelham Crookenden.
I was in contact with a member on Ancestry who manages a Tree for someone else, who advised me that many Bermonsey records were lost in the Blitz.

1871 census - absolutely terrible writing!

20 Stanley Terrace, Deptford
Sarah Crookenden Widow Widow 82 Dress maker retired Wickham Kent. I think that's what it says.

Is there any definite proof that the Sarah who married John Pelham Crookenden was the daughter of Thomas and Mary, or is that someone's best guess from searching for possible baptisms?

Okay, assuming that Thankful's real surname was Crookenden, not Bookenden, there is a baptism for him in 1761 at Chatham, Kent, but I guess that means Sarah was his nephew's wife, not his blood relative, so he isn't going to be a clue to her parentage!

There are quite a few missing chunks of the 1861 census, so we may not find Sarah on that one.

Ooh, there is a Sarah Maynard baptism 18 Oct 1789 at Wittersham, Kent. Surely that can't be a coincidence?! Parents' names Edward and Ann.

So I think the Sarah, daughter of Thomas, button maker, is probably not your Sarah.

There was a witness called Eliza Pascoe at John and Sarah's wedding. I wonder if we can find how she is connected. (The other witness was Albinus Crookenden.)
