Hi Jeanne,
She is so beautiful

I had to try and find her.
Sorry if you already have this.
Ada was born 1858, Hackney, 1b 355
1861 Census
Hackney
She is 2,with parents Jabez and Martha+ lots of siblings. Jabez born Wiltshire and Martha Derbyshire. + Margaret Gregory, sister ,aged 26.
!881 with the Cornishes as you said
Death ; Jabez Hibbard, Sept 1883, Hackney 1c 337
1891 she is with Mother Martha and brother Frederick aged 22 in Limehouse ( Martha is a widow and greengrocer) and Ada her assistant. Frederick is a bullion porter.
Cant find marriage/death either, unless mistranscribed.Also cant find her 1901 census.
