Thank you Shanreagh. Interesting information about Cornelius and Mary Crowley.
In the 1871 census Michael's age was recorded as 26. I haven't been able to find a census for Michael for 1861 so assume he was still in Ireland then.
In the 1861 census Daniel Crowley was 29, wife Mary 27, son Charles 10, daughter Honora 7.
In 1871 his age was recorded as 50. Mary was 40, Charles 17. Norah (Honora) 15 and they had Elizabeth 9, Daniel 7, John 5 and Bridget 3. They were living at the same address in both censuses.
In 1881 Daniel Crowley was 52, Mary 57, Elizabeth 18, Daniel 17, John 14, Bridget 13. They have moved to a different address.
Michael died tragically in August 1876 at the age of 34. His body was pulled from the Monmouthshire Canal in the parish of Llanocchora (Cwmbran). According to his death certificate there was an inquest (8 & 12 August) but Gwent Archives say there is no record of it and there doesn't appear to be a report in the local newspapers.
