Hello Andrew, nice to hear from another Keenan descendant. I have been researching the Keenan's for around 3 years, and have a huge amount of information on them. Margaret Keenan/Potts is my first cousin 3 times removed. Her father was Felix Keenan b1836 in Ireland. Felix's older brother was John b1835 and I am directly descended from him. I would love to see the photo you have of Hannah with 2 of her brothers. I suspect they may be James & Edward who also went to Australia. I have photo's which I can compare to, I am also in contact with descendants of James who I can put you in touch with if you wish. I am in regular contact with other Keenan researchers in UK, USA, Canada, Australia and Tasmania and we all pool our knowledge to discover more about a very colourful family. (where do you live) After you have posted 3 times on this site, you are then able to send private messages. We could then swap e-mails and I could then introduce you to your extended family. My main interest now, is to accumulate as many photo's, documents, will's, gossip, or whatever to try to colour in with more detail the social history of the family. If you don't mind, could I have the names and dates to link you o my tree to Winifred Potts, also, do you know anything of her sisters Margaret & Clementina.
Regards
David
