Judy Garland (born Frances Gumm) was not directly related to Ulysees S Grant - her Great Great Grandfather Hugh Fitzpatrick born 1809 died 1878 was married twice, Garland is descended from his son Hugh Fitzpatrick 1838-1908 by first wife Margaret Ross 1807-1845. After Margaret Ross died he married Catherine Grant in 1848 she was born in Quebec,Canada in 1830 and died in Cornwall, Ontario, Canada in 1915 . She was the daughterof John Grant 1783-1864 and JaeGlasford 1789-1880 it was Catherine that was a cousn of Ulysees S Grant so as you can see Garland being descended from the first family of Hugh Fitzpatrick ad Margaret Ross does not have shared ancestry with Ulysees S Grant. However on her Milne side through the 'Lovie' branch her family her descent can be directly linked back to Robet the Bruce and Stewarts and to Aoife MacMurrough and Strongbow in 12 Century Ireland. I suspect that if the family of Ulysees S Grant can be traced back to Ulster and before that Scotland there probably is a common relative through one of the Milne branches that includes; Lovie, Leslie,Matheson, Irvine,Scrimgeour, Seaton ,Douglas,Keith and many other ancient and royal lineages linked to the Stewarts andI would bet that there is a link to Gran. Hope tha this info is helpful.
