Why not learn the words to the song? Robert used to sing this song on our many road trips. "Comin thro' the rye" describes crossing a ford (watersplash) through the Rye Water (a creek) at Drakemyre, downstream from Ryefield House and not far from the confluence of the Rye with the River Garnock. It's just a funny, happy, folk song!
What's a jobber? That's what Robert did.
What battle happened near the river Garnock?
Patrick (Robert's son) was the last of the bloodline - he never had children - SO let's learn more about him HERE
