Tracing family tree

I am trying to trace my Family tree and looking for some help. My family it seems came from the Lurgan area. My G.G.Grandfather was Robert Thompson who emigrated to Hamilton, Scotland around 1900, his father was George who was married to a Margaret McCaig. Robert had a son who was called Ezekiel and in the census of 1911 I found an Ezekiel Thompson who was living in Hamilton Street, Lurgan Urban, Armagh, he was aged 50 years at this time, and I am wondering if he could have been Robert’s brother. Before the family moved to Scotland they were living in Finchs Court, Lurgan.

I had a few days holiday in Belfast at the end of February and visited Lurgan and the church in Moira where Robert Thompson married an Annie McMurray in 1862. If anyone out there has any information at all about my family I would be very grateful to hear from you.
