I was so interested when I clicked on to your letters ref. Lingen-Burton's of Longner NOT Longnor----my dad's uncle was Edward robert Lingen-burton--he was born in South africa in 1866 ---they lived in Suffolk but after his marriage to my Great aunt they moved to shropshire around the very early 1900's and lived at Ford House Shrewsbury.
Rev.robert Lingen Burton lived at Llandewi Hall in radnorshire which I believe was very grand in those days but then became owners of Ford House and Ford Mansion shropshire--later it was occupied by Rev, Francis Lingen-burton who was a priest in shrewsbury. then as I said my Great Uncle and Aunt with their 2 children ---edward robert and Edith Maria Eva Lingen-Burton who were my Dad's first cousins moved there to live. Thsy are definitely the same family as Longner Hall but not sure 'what relationship'. The name Edward robert Lingen-Burton is very prevalent in the Longner family!! I have a cousin living in Hereford UK who is Edward Burton Cottey ---he is the son of Edith Maria Lingen Burton my Dad's first cousin------gets very complicated but interesting!
Look up Families of Llandewi Hall Radnorshire --radmorshire society transactions----you should find this interesting.
Love to hear from you
