Hello! I've loved reading all this information! Mary Brown Hazlett, first daughter of Robert and Jane Brown, is my third great-grandmother. Mary married Thomas Hazlett (9 June 1803-14 March 1896) on March 26, 1826, and had 14 children. Their ninth child, Samuel (1846-1921) is my great-great-grandfather. He married Catherine Torrens and they had one son named Samuel, but later he married Nancey (Knox, maybe?) around 1875. Samuel and Nancey lived in Moneydig and also had 14 children, and of course, named all of their children after his siblings. Their tenth child, Mary (21 April 1889 - 26 Feb 1968), married my great-grandfather, Walter Smyth (18 August 1883-27 August 1964). Walter and Mary moved from Ireland to the Philadelphia area in 1907 and had two children. Then they came back to Ireland around 1915, had two more children (one of whom is my grandfather, William Smyth [4 October 1920-22 December 1984]), then in 1922, went back to PA and had another daughter.
I thought I'd try to fill in some blanks about Robert and Jane's children, especially since there didn't seem to be a lot of information about Mary Brown Hazlett. Not sure if it helps at all!
