If we can believe writer Benjamin P Thomas in his book STANTON on page 68, Pittsburgh lawyer Edwin M Stanton married Pittsburgh socialite Ellen Hutchison a descendent ot Meriwether Lewis of Pittsburgh.
Edwin M Stanton was Lincoln's Secretary of War during the Civil War.
Susan would be ne of the family names I believe connected to Major Lawremce Lewis and or CSA Col Meriwether Lewis Clark.
There might even be a connection to General Harry Halleck who married Elizabeth Hamilton the granddaughter of Alexander Hamilton.
Anyway thse are all the Pittsburgh families connected to Meriwether Lewis and his boat builders.
