US presidential race hopeful Sarah Palin can trace her family tree back to 18th century NORWICH, historians revealed last night. The Vice-President candidate’s great, great, great, great, great grandfather Robert Gower was baptised in the Norfolk city in 1723, according to ancestry.co.uk. Gower, who is from her mum’s side of the family, then left for the US in the 18th Century, and his son James was born in Maine. Mum-of-five Palin, 44, dubbed the Republican Pitbull in Lipstick, also claims an Irish connection, like Democrat rival Barack Obama.
