This is what I have on Anthony's pedigree to date, however I do have quite a bit on his progeny: M_McLean

1. Robert2 McKain/McCain (McKain/McCain/McKane/McCane/McKein1) was born Bef.
1765 in Ireland., d. abt. 1830. He married Unknown. She was born Bef. 1765,
and died Bet. 1820 - 1830.
I first found Robert(1), John and Anthony in Dearborn County, IN. in 1820
Children of Robert McKain/McCain and Unknown are:
2 i. Robert3 McKain/McCain, born Abt. 1785 in
Ireland. He married Unknown; born Abt. 1785 in Ireland. (Connection assumption)
3 ii. John "Andrew" McKain/McCain1,2, born Abt. 1787 (proven)
in Ireland; died 1849 in Ohio Co., IN. He married Margaret Duncan3 Bef. 1820 in
Pennsylvania/Indiana???; born Bet. 1790 - 1800 in Pennsylvania; died Bef. 1850
in Indiana.
In 1840 a female 10-15 years was living in this family. I
believe it to be his sister, daughter of Robert and Unknown, since I can no longer find them.
4 iii. Anthony McKain/McCain, born Abt. 1790 in Ireland; died Bef. 1860 in Ohio Co., IN. He married Catherine(Katie) Nelson Abt. 1820 in ???; born Abt. 1800 in Ireland; died Aft. 1880 in Aurora, Dearborn County, IN.
5 iv. Daughter McKain/McCain, born Bet. 1810 - 1815.
Notes for Daughter McKain/McCain:
I think her name might have been Elizabeth.
