Hello....

Ellinor /Eleanore (So many different spellings ) was the daughter of RC Bourne
According to the baptism record it implies she was illegitimate as only her mother's name is recorded as Sarah Ann Glew, I think Richard Bourne took her on as his own when he and her mother married.
Births Mar 1851
GLEW Eleanor - Radford 15 697
Marriage at Radford St Peter - 19th January 1854
RICHARD CARMICHAEL BOURNE & SARAH ANNE GLEW
I have never found any records of Ellinor after Alexander died
There was one thing that I thought was a really weird coincidence...... was this marriage....
Harington Eleanore - Kensington 1a 298
One of the grooms was a Herbert Thomas EDWARDS and then finding that in 1881 Eleanor was in the household of an Edward's family and one of their son's was a Herbert Thomas Edwards.
1881 - RG11/1058 / 67 / 8 - Ashhurst Wood, East Grinstead, Sussex
Herbert Thomas Edwards is only 21 and given as single and Eleanor Harrington a widow, aged 30 and a Lady.
