There was a Celia Bonnah/Bonin/Bonnin born to Joseph Bonnah and Mary Ward in 1852. That Joseph Bonnah was born abt 1812 but some records have him born as early as 1800. Celia married a George Letts. I have seen the name spelled many different ways but never Bannaugh. I have quite a bit of info on the Bonnahs if you wish to see it.
