Hi M

Not from a directory, but there is a marriage on Lancashire OPC for a daughter:
3 Oct 1850 St Martin in the Fields, Vauxhall district, Liverpool
Joseph Dickman - Full Gilder Bachelor of Church St
Rosanna O'Brien - Minor Spinster of Elgin St
Groom's Father: Thomas Dickman, Mariner
Bride's Father: James O'Brien, Gilder
Witness: Edward Dyas, (X); Margaret Condon, (X)
http://www.lan-opc.org.uk/Liverpool/Vauxhall/stmartin/marriages_1848-1859.htmlSo if that is the right family, he might have been at Elgin St in 1850.
According to 1861 census, Rosanna was born in Liverpool around 1833
