If anyone could help me find the parents of a Robert Costain born 1819 - 1820. He died March 1868 aged 49 & was married to Anne Archibald. I have a probable marriage date in Malew for R & A on 15th Dec 1844. Family search only gives after 1821. Ann was about the same age as her husband. In the 1851 census Robert was aged 31 & was a roper in Douglas. Thanks for any info.
