Premise: Marks was a manor house located near Marks Gate at the northern tip of the London Borough of Barking and Dagenham in London, England, the house standing on what is now Warren Hall Farm. The name Marks (historically Markes) is believed to have been derived from the "de Merk" family who build the original manor in the 14th Century. The manor house was demolished in 1808
Hypothesis: The de Merk family never lived in the manor
