Victoria, I have long wondered the same! There might be paintings of Andrew, Gilbert McKown and Jane Crawford McKown, somewhere. And Phoebe Casto McKown and James McKown lived long enough to have been around for a daguerreotype. The rest of them down the line would have been photographed at least once, I would think.
Who has these items??? I hope they aren't forgotten or overlooked in an attic or a basement.
My 3rd great grandfather, Samuel McKown (husband of Margaret Rush), was a younger brother of your Gilbert (husband of Lydia Flesher), both sons of Phoebe and James.
