I'm sorry I didn't see your question sooner, before your great-uncle Sidney Lewis passed away. I have not been on the McHargue GenForum in a while.
Vera, Mona Pearl, and Sidney Lewis were the children of Fisher Boyd McHargue and Ethel L Cook. Boyd was the son of Lewis Henry McHargue and Sarah Jane Fowler. Lewis was the son of William Lewis McHargue and Sarah Jane Morris. William was the son of Seaborn McHargue and Margaret Ann Barron. Seaborn was the son of Alexander McHargue and Christina Barron. Alexander was the son of John McHargue and Margaret McBroom. John McHargue, who was a patriot soldier in the War of Independence, was the son of Alexander McHargue, who was from Ireland or Scotland.
