My Livingston family of Sligo married to Whyte but I don't have the same names. Earliest marriage was gt-gt-grandfathers brother William b c1829 who married Maria Whyte in 1854. Nothing further known.
However it is the next generation for which I know more. My gt-grandfather's older sister Ann Livingston b c1846 married 1869 to George Whyte who died about 1922 in Sligo. You can find them in Rathbarron in the 1901 census. George's father was John a farmer of Mentuagh.
Their children were Maria b1870 married Tuach, John b 1871, Thomas c 1872, Richard bc1874, William b c1878, Isabella b c1879 m Devlin, James b1884, Anne b 1886 & George b 1889.
