Hi Mckay734,
I'm not 100% sure but I think I may have located your Robert McKay. He's to be found on the 1841 census living Cleveland Street, Hartlepool, Stockton & Sedgefield, Durham, England. He's with Ann, Martha and Leslie (the transcriptions say Lester). This is the only census Robert is with his family as by 1851 Ann, Martha and Leslie are back living in Aberdeen. By 1861 Ann then aged 49 and Martha aged 26 are living in Fraserburgh. Ann died in 1869 and from her death certificate I know her name was Ann Leslie Couper, daughter of William Couper and Martha Fraser.
Ann's Birth:

I think I'd want to see the OPRs to see if they offer any clues.
