Kneebones- hunting Pathena from Maker

Despite the name change we're also Kneebones. Our Kneebone family came from Millbrook /Maker in Cornwall and moved to Stoke Damarel in Devon; Pathena and her son John came to Australia in 1889.John was her only son, however we believe Pathena had brothers in UK . Are there any other families with a Pathenain their tree?We believe her mother's name was Mary Ann DOWN and her father John Kneebone.
