It was Walter Alfred that got me interested in this line.
He was baptized Cowley in 1866, appears as Lawson 1871 and 1881, reverts to Cowley in 1891 and 1901.

His mother was Elizabeth Callister, widow of John Cowley (died Nov 1861) - have not determined his father.

In 1861 John Cowley has his uncle Hugh living with him. Hugh was, presumeably, the brother of John' s father. Hugh married Catherine Lawson.

I'm fairly sure that John's parents were John Cowley & Esther Sayle (children John & Thomas)

So, I'm now looking for a Cowley family that includes sons John & Hugh, born around 1780-90, probably in the Ramsey/Lezayre area.
