I recently bought a New Year's card at an antiques market from an "Evelyn" to Sergeant Major C W Maynard. 509th. Battery. Royal Field Artillery. l believe it dates from WW1 but beyond that l have no knowledge of this man and despite my best efforts via "Ancestry" have been unable to throw any light upon who he was, where he served or whether he survived the War or not, anyone out there with any relevant information l would love to hear from you.
