My gg grandmother, Margaret Bridson, b 12 December 1839, Patrick, IOM, had a sister, Esther, that immigrated to Rochester, NY, and married Edward Qualtrough. According to old family letters in my possession, they owned a greenhouse.

Margaret and Esther had three other sisters, Christian (married a Mr. Johnson & remained in IOM) Kate (married Philip Radcliffe, in California), and Elizabeth (married a William Bowden, Hurley, WI)

Esther's parents were Jane (Mylchreest) and Richard Bridson.

Jane's parents were Mary (?) and Richard Mylchreest.

Sorry, I have no dates or other info for any of the above. As I mention, this is all documented in an old family letter.

Cheers... and happy hunting!
