I'd be interested in sharing information with anyone working on this family. My 2xgreat grandfather James Lang was born in 1815 in Houston and Killelan(West Glen I believe) His parents were Gabriel Lang (b. c1784 and likely died bef 1851 census) and Elizabeth Patereson (b. c1783 and died 4 Jul 1854 Abbey Renfrewshire) James married Margaret Jack (b. c1817 and died 3 Jan 1900 at 15 Kempock, Gourock. They married 5 June 1841 in Kilbarchan, Renfrewshire. They had 10 children. My great grandmother Georgina Jane Lang (1842-1918) was their eldest daughter. Her siblings were:James b 1844, Elizabeth Paterson b 1846, George b 1849, Gabriel b 1851, Margaret Stewart b 1853, John Boyd b 1855, Janet b 1858, Wm b 1861 and Malcolm b 1862.
Looking forward to making some connections,
