Maybe not in your line but there was a George Black born in Ireland abt 1821 who married Margaret Gawne (1825 Ballaugh) in Douglas, 11 Jun 1850.

Children:
John abt 1850 Ballaugh
William abt 1852 Douglas
George abt 1854 Douglas
Mary Ann abt 1856 Douglas
Samuel abt 1860 Douglas

Margaret died 1864 and George remarried to Sarah in abt 1866 and had five more children: Edward abt 1867, Frances abt 1869, Ellen abt 1870, Sarah abt 1875 and Agnes abt 1877 all born Douglas.

George died before 1891 and Sarah in 1908.

I can get more details if required.
