Elizabeth Walton's daughter Mary Ann Walton b. 1828, Leeds (Possibly Leeds Barracks?) - married Walter Sicklemore in 1851 at Tuthill Stairs Chapel, Newcastle but father's name missing from certificate.
Wow, a Sicklemore! Don't often get one of those on here.
Do you have them in 1861?
In 1871 they have a Joseph John Walton, 20, with them

So the only tangible sign of Levi Walton is him being on named on Elizabeth's death certificate as her husband?
Levi only appears on the death certificate. A mystery man who could be a son/nephew... I have trawled military records and births/deaths/marriages but found nothing. It could be that Levi Walton was from an unrelated Walton line? In the absence of source documents anything is possible.
There are paper trails for Walter Sicklemore, Mary Ann Walton and Joseph John Walton. I even have a photograph of the Sicklemore residence in Leeds (etched glass panel over the front door - Sicklemore).
Joseph John Walton was Mary Ann Walton Sicklemore's nephew, presuming Levi was Sergeant Joseph's son i.e. Sergeant Joseph Walton > Thomas Walton > Joseph John Walton. Walter Sicklemore was a hardware travelling salesman and even visited my branch of the family in Blackhill, Co. Durham (Walter+Mary Ann staying in a pub for the 1861 Census - Robert Walton+Mary+Family within walking distance). Robert (born Brighton Barracks) was another of Sergeant Joseph's sons.
The Sicklemores came from London, my note:
Parents' marriage Robert Sicklemore + Maria Roles on 21 Jun 1821 at Hanover Square Westminster in London, England. Death Robert Sicklemore on 6 Jan 1855 in Bow, Middlesex, England. Marriage Q4 1885 Leeds 9b 813, RB/88/17, Walter Sicklemore + Ann Pearce.
These were Walter's parents and following the death of Mary Ann Walton Sicklemore he married Annie Pearce of Thame, Oxfordshire. Walter appears in the Census 1841 thr' to 1891 and dies 13 Mar 1898 in Leeds.
