William

I have just found your request for information on the internet and I believe my grandfather (John Edward Kennaugh) and your grandfather (William) were brothers.Our maternal great-grandmother was Eleanor Ann Holden.With regards to her husband, William, I don't think you will find any further record of him in the Island from about the mid 1870's as he seems to have left his family about then and it was thought he had gone to America where he may have had a brother. I found a reference in the San Francisco Morning Call newspaper index dated 1879 of a marriage between William Kennaugh and Anna D Clow, but was unable to check it. Maybe you could?.The Kennaugh's and Holden's from that time are buried in Braddan cemetery. Also with reference to Ethel, the Ethel in the grave at Braddan is one of my grandfather's) John Edward) children.
I hope this has helped you and if I can be of any further help as I have a little bit more information about the Kennaugh's.

Regards

Ken (Edward Kennaugh Convery)
