Hello Steve..It is also the same my husband's full name is written on our MC (2 Given names) which is the same written in his passport. It's just that his middle name is his mother's maiden name same here in the Philippines..I already emailed the embassy and go back again to the NSO for some clarification regarding with this matter..Hope everything is gonna be fine..
just a personal observation here british dont normally have two given names...the second name is normally their middle name. correct me if i am wrong. Better check the embassy asap as it needs court hearing to amend name on MC
