Well another few months and this post would have been ten years old. I was just starting my research then, William's parents are Andrew and Jane(Boden) Ritchie. I found his birth certificate obituary etc. after this post.
The correct spelling is Boden. William's last son was William Boden Ritchie. I have a wedding photograph of him and his wife. Are you a paid researcher? William Richie and Jane Henderson were my great great grandparents.
