My 2x gt grandmother Eleonor LANDER was born St Pancras c1841, father was George Moseley LANDER (solicitor)
I cannot find anything on her birth, who her mother was, when her mother died (?).
Her father married Honora SCANLAN, 08 Nov 1856, condition batchelor. (I have the marriage certificate.) George married again in 1868 this time recorded as a widower.
She married William INWOOD, 09 April 1859 in the parish church St Pancras.
Eleanor went to Australia, arriving Mar 1862 with her 2 daughters; her husband had arrived the previous year.
In the 1871 census Eleanor was back in England less her daughters. I connot find any trace of her after this. Husband & daughters remained in Aust.
Summing up, no Info prior to her marriage in 1859, & no trace after 1871.
