I have been researching other strands of this family.
John Clarke and Catherine Kavanagh married in Cavan in 1892 and Laura Crowley is their witness. She was born Laura Clarke around the 1860s, daughter of a showman called John Clarke. She also lives at Ash Street with her husband in the 1911 census. There was another John Clarke, musician, who had a Victor, Frederick and Josephine in the 1880s. I thought this John Clarke was the brother of Laura.. now its occuring to me that one of them may in fact be the father John Clarke
born perhaps 1840s remarrying.
