Hi Joe & Rhonda, firstly I am so sorry for the delay in replying to you both but been off the internet for 6mths. I have now found my William & Margaret on the census, thought were both dead by 1841. There is another child to this pair as well, Janet Kerr, born in Linlithgow @ 1816. If you follow her on the census, both William & Margaret are there on 41 census but only William on 51 census. Can follow Janet up to 91 census, although she is mistranscribed on 61 census as surname Ren, have tried to find her death but failed so far. I am assuming that William died between 1851-1855. On 51 census it looks like it says on image off S.P. born in Binnie & blind. Mistranscription on Ancestry.
Is Peter related to you Rhonda.
Many thanks to you both for your input.
Hilary. x
