Henry Lord and Catherine Kneale had seven children:

Esther (b 1784)

Catherine (b 1786)

John (1789)

Jane (b 1792). Married John Christian in 1811.

William (b 1794). Married Jane Corkill in 1817.

Margaret (b 1799). Married William Rothwell in 1825.

Thomas Henry (b 1803). Married Eleanor Quayle in 1824.

William and Jane had a daughter Catherine (b 1819). She married:

[1] Robert Cowley in 1840.

[2] John Curphey in 1848.

I would be very interested to know if your family letters make any reference to Catherine (aka Kitty ?), Robert Cowley or John Curphey.
