Martha Keen appears to be d/o John and Jane Keen was Christened 8 Aug 1794 at Saint Michael, Coventry, Warwick, England. In the 1851 census, Martha said she was born in Combe Fields which is 5 miles by road from Coventry (half that distance as the crow flies) and 10 miles from Kenilworth.
Combe fields is a parish with scattered houses, but no village. The ruins of a twelfth century abbey and the local manor were both owned by the Craven family. There are still several farms in the area so I am guessing John Keen was a farm labourer. Parishmouse advises people looking for ancestors to check the surrounding villages (Withybrook, Binley Walsgrave on Sowe, Ansty, Brinklow, Wyken, or Monks Kirby).
Reasons:
All IGI searches of Withybrook, Binley Walsgrave on Sowe, Ansty, Brinklow, Wyken, or Monks Kirbyled to John and Jane Keen who christened their daughter Martha in Coventry in 1794.
Martha's marriage certificate indicates she would have been born in 1792 or 93. If this is the correct girl, she may have been about one year old when she was christened in Coventry - but people of this era often were not that accurate on birth years.
She would later name children 'John' (2nd son) and 'Jane' (2nd daughter).
She married John Munro 22 Aug 1813 in Kenilworth, during 1813. (John Munro Age 21 (born 1792 pr 93) residing at Ashow, Warwick
married Martha Keen Age 21 of Kenilworth, Warwick)
