Hi,
I have looked at the 1871 census for the address you mentioned and have found the following:
RG10/3778 folio 81b page 28
civil parish Liverpool, municipal ward Gt George, ecclesiastical parish St. Barnabus
10 house, 2 court, Jordan Street, Liverpool
Adam Hannett Head 25 Dock labourer Ireland
Mary Hannett Wife 24 Ireland
John Hannett Son 6 Liverpool
Sarah A Hannett Daur 4 Liverpool
Mary J Hannett Daur 2 Liverpool
Sarah Hailey Mother-in-law 60 Ireland
I know you put the name as Sarah Healey and it may be that but on the 1871 census it definitately looks like Hailey. There were also a couple of lodgers in the household.
I hope this is of some help to you.
