Have already tried a query to find these two but here they are again for anyone who may be able to help:
William Mark(AKA Mark) Faulkner b 1854 London City(Father Mark, an Engineer), Married(1882 Notting Hill/Kensington/St.Mark) a Sarah Ann Isaacson born 1863 suffolk(Father William, a shepheard). Cannot find them before the 1891 census(East Findsbury, London) 1901 census(Red Lion Passage, London), they seem to have appeared out of thin air!
