>>Staff at the Clare Heritage Centre at Corofin have discovered that the three-times world boxing champion's great grandfather was Abe Grady who was born in the town Ennis in the 1840s.

That would be more than just a great grandfather. It'd be great great I'd think.

Actually, it could be okay. Humor these hypothetical dates:

IF Ennis (Great-Grandfather) was born in 1848;

IF Ali's grandfather was born in 1880 (Ennis would be 32 yrs old)

IF Ali's father born was in 1910 (g-father would be 30 yrs old)

Ali was born in 1942 (father would be 32 yrs old)

This is reasonable.
