Little is known about the BRENNAN family - It is presumed that they came from Ireland to London during the famine.
John (jnr)'s marriage certificate gives his father's name as John (a mason).
On the 1891 census, John gave his birthplace as Kilkenny, this is the only known evidence as to where the family came from.
Kilkenny is famous for its marble quarry, this fits with John (snr)'s occupation.
