I am a great - grandson of Anthony Malarkey's older sister, Catherine Malarkey McAndrews. So that makes us third cousins. I've been a correspondent of Ed Logan's over the years. He has much more information than I do on the Malarkeys, however (ironically as he has concluded, after doing it all, that he is not in fact descended from that particular family). Feel free to contact me if you have any questions about Catherine's descendants. My tree is private but I can share it with you if you wish.
