Looking for Robert Day, drove for R.H.Stevens Transport

Dear forum,
Please can you help. We are trying to locate a long lost family friend. His name is Robert Day, he’ll be approximately 70yrs old and lived in the Macclesfield area. He drove for many years with R.H.Stevens Transport. It is my parents 50th Wedding anniversary this year and Robert was an usher at their Wedding. We are trying to track him down in order to invite him to the party. Not sure how these forums work… so any help in posting or forwarding this message onto the right area would be greatly appreciated. Many thanks Graham
