Well, that's a lot of information and questions.
Ellen's maiden name was Carroll and her father was Thomas Carroll and her mother Ellen but she was previously married to Thomas Hogan in November 1865 in West Bromwich, Thomas died.
She married John Hickey on 20 August 1877 in Southwark.
Yes that is them in the 1871 and 1881 census, unfortunately Eliza only made it to 7 years old.
In and out of the workhouse from 1887 is possible, I haven't found a date for John Hickey's death yet, Hickey is not an uncommon name. I'm still looking.
I think that's all the questions answered, now I'll follow up on suggsetions.
It was interesting that Bridget was also in the workhouse, I assume when she was too old for the school.
And just when I was about to respond along come another 6 replies which gives me some more great leads. Thank you all so much
