Did you ever find out any more about your Blythes in Kinross? I have a David Blyth married to Helen and having a daughter, Eliza (Elizabeth) Blyth. She was 70 when she died in 1900. She married John Grainger in Kinross in 1861. Any chance ogf being related. Eliza's son and family immigrated to Australia in 1917. I'm wondering if they already had family here.
