TindallEnglish From Tindale, the name of a town in Cumbria, derived from the name of the river Tyne combined with Old English dæl "dale, valley".
WindsorEnglish From the name of a few English towns, one notably the site of Windsor Castle. Their names mean "riverbank with a windlass" in Old English, a windlass being a lifting apparatus. In 1917 the British royal family adopted this name (after Windsor Castle), replacing their previous name Saxe-Coburg and Gotha.
