RIGHT !!  here we go again !!
1891 Census
RG12/2968
123 Braemar Street
Kirkdale
LiverpoolThomas LANGDON/Head/38/Coal Cleaver/Ireland
Catherine LANGDON/Wife/49/Ireland
Michael LANGDON/Son/15/Liverpool, Lancs
John LANGDON/Son/11/Liverpool, Lancs
Catherine LANGDON/Dau/5/Liverpool, Lancs
Thomas LANGDON/Son/3/Lierpool, Lancs
John HEALY/HEANY/Step-son/22/Dock Labourer/IrelandSo Catherine was married to someone called HEALY/HEANY before she married Thomas, which would explain the difference in their ages.  I couldn't find their marriage in England.
I couldn't find them anywhere on the 1881 Census either, so god knows where they were hiding !!
I assume your ancestor is John b. 1879, and if you have his birth certificate, then you might find more info in the Church baptismal records.
Happy hunting !
