Michael Leonard, born about 1821, and family.

[Sailor Sam]

Extract from 1871 Census. 9 Gray St., Silvertown, ED 12A, W‘Ham
Michael Leonard 50 not at home b.UK; wife Ellen 48 b.Ireland; son John 19 b.CityofLondon; daughter Mary Ann 18 b.ditto; son Daniel 16 b.ditto. 
Daniel Leonard, my ancestor, marries Maria Taylor next door at nr.8 and they have left an excellent record trail.  On their Marriage Cert it states: “Father Michael Leonard,  blacksmith”. 
My instinct says that both parents are Irish but I cannot find any other record of Michael and Ellen Leonard or even their childrens’ births in English GRO index.  Maria’s roots lay firmly in Cornwall but I would love to find some Irish ancestors.  Some experienced help would be greatly appreciated.

Michael Leonard 50 not at home b.UK

I think that is probably NK (not known) rather than UK.
