Good morning Ned. 'High House, Hugill: A Short History' is a short book with a section entitled 'The Jenkinson's'.The house was bought by William Jenkinson in 1698.It states that 'the overwhelming legacy of the Jenkinson clan appears to have been a high propoensity for procreation outside of wedlock and a tendency to beget twins' - it then goes on to provide some detail, centred on the mid-eighteenth century, to support this claim.
The Jenkinsons sold High House around about 1849.Thomas Jenkinson, the final Jenkinson owner, lived to the age of 91, and his son, was probably too old to take over.
