I've had help with Robert Costain who md Ann Archibald but now I'm stuck with Robert's parents. I have them (not verified) as Robert Costain md to Mary Christian In St Annes, Liverpool on 19th May 1817. In my notes I have Robert s/o John Costain & a Mary. and Mary Christian d/o John Christian & Elinor Bridson. Mary Christian I have born in March 1792 Malew & the Robert Costain she md born 1794 L'pool and died 1847 L'pool. I have found on Brian's list a Mary Costain death in Malew in 1847age 58. No idea if this is the right Mary as if both died in 1847 why is one in Malew & one in L'pool. There is a Robert costain burial in Malew in 1867 age 61 but that doesn't tally with his birth year. Any help would be appreciated. Thanks
