Thank you to D.J.Douglas and Frances for your quick responses,your help is greatly appreciated.My Great Grandfather's given names were John Henry PRESTON.
I've also discovered Anthony Preston who in 1671 was a soldier stationed at Rushen.There is also a Richard Preston from Ballacurry 1863 list on a church document from the Rushen area.
Can anybody else provide me with more information that will help me fill in the missing spaces/links?I am trying to unravel this from Australia.Thank you!
