Hi Jim,
The Gove and Watt family in Kincardinshire has many sons that have similar names.
For example there are 2 Andrew GOVES both of Johnshaven, Benholm. One born on the 5th of July 1849 the other in Oct 1851. I believe these 2 are cousins, their parents William GOVE and John GOVE being the sons of William GOVE and Christian nee MUFFERT. A number of researchers have recorded the Andrew born in 1851 as the son of William GOVE and Elizabeth WATT; when in fact he is the son of John GOVE and Catherine nee DOUGLAS.
I have seen the names you mentioned but have not looked to see if they are closely connected to the family line I have researched. One of the problems I found in researching the line I have followed is that the children seem to leave home in their early teens or even earlier. Just why this is the case I have not been able to determine. The William Gove and Elizabeth WATT family that I have researched had seven children that I know of. Of these only one remained in Scotland. James, William, Robert and David all migrated to Gippsland, Victoria Australia. Elizabeth Law McEWAN nee GOVE married to James McEWAN a plumber and her brother Andrew GOVE a plumber migrated to the Detroit Wayne Michigan area. Helen KEILLER nee GOVE lived at 19 Market Street, Perth, Perthshire, Scotland.
It is quite possible that there is a link going back perhaps to William GOVE and Christian MUFFERT, but the records get much harder to determine around that era unless one is able to find death and marriage certificates.
If you are able to find a connection then I would be interested in hearing from you. However I have just about concluded my research into the Gove family.
My interest was due to the fact that my grandfathers sister married a John Lawson GOVE, and that I lived in the Sale - Clydebank area as a youth where the Gove men had farms. My uncles worked on these farms when they were young men before world war 2.
If I am able to help you with details I am happy to share.
Kind regards
Leon
