If your g.grandmother Ann Brown, was dau of Andrew Brown & Isabella Ball, then according to my findings, she had a brother Andrew Jr, born about 1856, still not married in 1901, and a brother Henry born about 1858, not married in 1891. Three Brown families lived next door to my Archibald Laverty family from about 1836 to at least 1891. Isabella was a widow in 1891 and son Henry was still living with her. There were 2 Henry Browns, one Andrew & Isabella's son, and the other a son of John Brown & Eliza Mitchell, and a brother to Robt J. married to Grace Colquhoun. One of the Henry's married my Jennette Laverty. Henry & Jennette are buried in SandHill Cem., in Pittsburgh Twp., Frontenac Co. Henry and Jennett had 2 sons, Wilfred born 1886 and Oswald born 1898. Did Henry work for the railroad? If so, then they were in Cornwall in 1891 and in London in 1901. Have we made a connection?!!
