Interesting to see (yet again) the inexorable link between Lalor and Dunne. Peter Lalor the famed rebel leader of Eureka Stockade was married to Alicia Dunne; my ancestor Fcs Wm Jos Breen Hanlon was a cousin of Peter Lalor tho' unsure how this is the case, BUT various memos state this (credible obituaries etc) as well I hold a piece of the relic flag of the Eureka Stockade given by Lalor to his much beloved cousin Hanlon (my grt g'father)... whatever their family ties these men were bosom buddies.
My remark is more a chat than info , sorry. I am curious to know where your line is, USA or Ireland or Australia seems the 3 main likely options.
There is a Kennedy tie-in also we have not yet nailed. A Jesuit priest Kennedy was also named as cousin of Peter Lalor in the latter's obituary in the Argus newspaper of the era.
