Hello, Little Plum,
My McGuires were mostly from Saltcoats. Bill McGuire was my grandfather, and lived on Ardeer Cresc. He wroked at Ardeer, but before that was a bus and taxi driver. He was a hobbyist mechanic. His brother Jack (john) had a garage in Dalry and was a mechanic. There were other McGuire brothers, Jim was one, and Pat, also Joe and several girls, but I am not certain if that Jim was the same. Just may have been. I will check it out.
One was a government overseer at the factory.
I am not sure about Anne. Our McGuires went to St. Mary's in Saltcoats and St. Johns at Moorpark west Steventston. Billy and Marion McGuire were my cousins from Hawkhill place stevenston. I'll check in that for you though and see if Jim ever worked there (doing my genealogy) might take a bit though to find the info
Thanks for writing,
Cheers,
June
