In 1841 I believe Jane is living in Kirkandrews upon Esk, 10 years old, with John Robson & Mary Robson (nee Tinning) and their son James Robson.
As Mary Robson is also living with Jane (now Percival) in Netherby in 1861, I suspect, but I havent been able to prove yet, that John & Mary Robson are Jane's Grandparents. There are baptisms for two children belonging to John & Mary Robson - Betty 1802 & James 1804 both Arthuret but I am unable to find a baptism for a daughter Mary Robson.
From Jane's marriage certificate 12 Nov 1853 Rockcliffe to John Percival, her father James Black, is a labourer.
Here's where it gets complicated...
James Black & Mary Robson married in Gretna 9 Jun 1832 and also 26 Jan 1833 in Kirklinton.
Witnesses were James Robson and Sarah Tinning. These witnesses confirm that this Mary Robson is connected to the Mary & John Robson Jane is living with.
There is a James Black & Mary Black living in Kirklinton in 1841. I suspect this James & Mary Black are Jane's parents.
By 1851 James & Mary Black are in Walton Le Dale, Lancashire with a family - John 8yrs born in Ellel, Lancashire, Betty A 5yrs born in Ashton, Lancs, Mary 4 yrs born in Ashton, Lancs and Jane A 3 months born in Walton Le Dale.
In 1861 the family are in Condover, Shropshire with two new additions Margaret 8yrs born Walton, Lancs and Sarah 2yrs born Condover.
In 1871`& 1881 they are in St Mary Redcliffe, Gloucesterhire.
This is definitely James Black & Mary Robson as I sent for the birth certificate of one of their children and it confirmed mother's maiden name as Robson.
So, I am looking for
1) Jane Black's baptism which will hopefully confirm that Mary Robson is her mother and my 3xGGM
2) Mary Robson's baptism (1812-1818 Arthuret/Longtown) which will hopefully confirm John & Mary Robson as her parents and my 4xGreat Grandparents.
Hope this all makes some sense
