Hi, Louise, This is the information I have found from the Cornwall OPC regarding Kellows.
James Kellow married Susanna Hambly 24/11/1781 in St Teath Their children's baptisms were: Both St Teath James 18/3/1782 Mary 27/11/1785
Susanna died 27/4/1791
James then married Honor Rundle 11/12/1791 in St Teath Their children's baptisms were: All St Teath John 1793 William 1794 Moses 1797 Phillippa 1803 Robert 1805 Elizabeth 1806 Margaret 1808 - died in infancy Simon 1810 - died 1810 George 1812 Jane 1814 - died in infancy.
I have a Phillippa Kellow c 1803.I an assuming that she was the daughter of James and Honor. She married William Langdon in 1830 in St Teath.Their son James Kellow Langdon, c 1840 married Eliza Honey.They were my G G Grandparents. I have found a few instances of Kellow/Honey connections.I have quite a lot of Honeys in my tree. Hope this is of some help. Regards, Val.
