Roger & Patricia - many thanks for the information - it is much appreciated.
I have checked through my research and Michael & Mary Galvin did have a child called Patrick who was born in 1842, which I have checked from the 1851 census.
I can't locate an Anne Galvin. I did wonder if family members still exist in the area.
There were also other children born in Ireland most of them recorded on the census: Sarah (1840) Bridget (1845) Doha (1845) Delia (1845) and Margaret (1951) aged 3 months old. Suggests it was early 1851 when they migrated to Lancashire. Doha and Delia do not appear on the 1851 census. Wondered if they had triplets?
The name Heavy is recorded as that spelling on the census records, but family info passed down has it spelt Heavey. Was there a variation in the surname?
I have looked further back for Michael's and Mary's parents and found records that might match for Michael's parents as: Patt & Honoria Galvin from 29 Castle & Spiddlegate, Athenry, Galway and Mary's parents as: James & Rose Heavey (with an e) from Correnarty, Kinawley, Cavan. This was from the 1821 Ireland census and the age gap between Michael & Mary seem to match, although I can't take them as accurate when recorded.
Any further information would be most welcome as I have now built up a very comprehensive family tree. My Irish roots which are very strong on my DNA test has really caught my interest and attention.
Also, any information on the Abbey at Abbeyknockmoy would be interesting as I also have a very keen interest in heritage.
Thank you again.
Andy.
