Hi Gill,
In short I don't know whether you have the same Cowlishaw family as me, but it IS very likely. I have a Mary Cowlishaw, born C1675, and married to George HILL 15 March 1695, in Alfreton, which is very close to Wirksworth. Indeed, George came from Crich, in the parish of Wirksworth. Mary died on 14 August 1728. Again in Alfreton. The couple had 7 children that I know of, one of whom, John HILL is my direct descendant. If I can help some more please let me know. Best wishes.
Martin
