We find no birth records for William Fleming Sinclair in Moneyconey, N Ireland where most of his siblings were born, but we know one of his brothers, Josias Sinclair, was born in Bridgeton, Glascow, Scotland in 1868. We wonder if William Fleming Sinclair might have also been born in Bridgeton, Glascow. His birth would have been between 1860 and 1864 to William Brown Sinclair and Margaret Jane Barnett. The month and day are very likely November 11. Best guess for year would be 1862. Thank you for any help you can give.
