Thank you for your e-mail.My only knowledge of Ted Couling is his name from the 1881 Census. From my family I have recollections of their life in the Sleaford area, but I have never heard of his name mentioned. In 1918 Ted would have been 51, in the right time scale.I am sorry I cannot help you further on your research.
Have you contacted the Lincolnshire Records Office in Lincoln? They have provided details for my research in the past.I have also done a search of the name on www.bt.com (directory enquires), and there is listed a "Roy Couling, 10 Quinton Close, Bracebridge Heath, Lincoln.There is also Couling's with phone numbers in North Hykeham.There may be a connection to Ted Couling there.
I was surprised that you live near Lincoln, I have had several enquires about the Couling name over the past 5 years and they have all been from the USA and Canada.I answered you first query on the basis that you came from that area.
I live near Cardiff now but lived at Radcliffe-on-Trent for 7 years in the late 50s.Hoping you are successful with your research.
