Looking for the Rodden Family from Termon Donegal

My great-great-great grandfather was Edward Rodden (born c.1812) and he married Bridget Mcgarvie.

They had two sons that I am aware of: Charles born in 1840 and Edward born in 1842. Charles and Edward later moved to Kirkintilloch in Scotland, which is where my mother (and I) were born. Charles married Sarah McDermid (from Argyll in Scotland). They had quite a few children, the youngest of whom, William, is my great-grandfather. William died (killed in action) in the Somme region of France (in 1917), when he was a private in the British Army with the 6th battalion of Gordon Highlanders. William had 4 children with his wife Sarah McKinnon - the children were John, Morag, Charles and Mary. Charles was my grandfather and he served in WW2.

Any information about my ancestors would be gratefully welcomed.

Thanks in advance

Mark
