I am not a Calder descendant, However, I have the Simcoe family of William Calder & Isabella Fletcher in my family info. William Calder was b.1846 Coilabus, Islay m. Isabella Fletcher in Simcoe ON in 1873. William Calder d. in 1904 in Manitoba. children - Tom (b.1875) & Catherine (b.1876) in Ontario; and Alex (b.1880), Jack /John (b.1881) & Isabella (b.1886) in Manitoba. A few years ago, I corresponded with Ted Larsen about the Calder family. The remainder of my data was taken from Ted's data on-line. >From the marriage record of William & Isabella the parents of William are stated to be Thomas Calder & Cathrine Calder. Thomas Calder (b.1799, Islay) & Cathrine Calder children - John (1843), William (1846), George (1848), Flora (1850), Thomas (1857) Parents of Thomas Calder (1799 - 1867) appear to be William Calder & Catherine Bethune children Mary (b.1796), Thomas (1799), William (1811) Does anyone have any info on Cathrine Calder, wife of Thomas Calder (b. 1799) Islay?
