Found Andrew Buchanan born Fintry 1879. He is on Census of 1911 as living in Bellshill, Lanarkshire. He married Janet McLennan of Carluke, Lanarkshire in 1906 and by 1911 had two sons Andrew aged 6 and John aged 2. He died in 1947. It is also possible they had a daughter, Jane born 1915. The same names are repeated throughout the family. Still no luck with his sister, also Jane, born 1889 in Cambusnethan. She appears on 1901 Census in Cambusnethan but not on 1911. I have tried marriage records and census records for whole of Scotland but too many possibilities. She possibly went into service as her Mother had done before her. I'll keep plodding on. Of the nine children Jane Buchanan/Brownlie/Docherty had I have managed to track down six, so still a way to go.
