I have George MOCATTA and Agnes MOCATTA née GUEST in Birkenhead. Married 1901. 3 daughters born 1905-1910. None of the daughters married. George was in wine trade. Related to architect of Brighton railway station - presumably to bankers too. George's father's family came from Chester. His mother is my relative - Georgiana MANNING.
What the connection is to yours - who knows, but perhaps this helps.
