Catherine Brosnan

[SuG]

Sadly none of these are feasible. Catherine was born in Kerry around 1857-8, likewise Thomas Mcdonald in Carlow.
All of their children were born in London.
Both are buried in paupers graves in the same cemetery in north London, Catherine in the catholic area,Thomas in the Protestant area.

Thanks for those names and links. They don't seem to have named any child Timothy after Catherine's father. There is another magic way you can find relatives. That is by doing your DNA. Have you thought about that all all? I have found it very useful.

I think the first is a reference to Edward McDonald/McDonnell who was apparently staying with the family in England. Aged 25 and born in Ireland.  Not sure if you are searching for the family of Thomas McDonald/McDonnell but there are refs on this site, just search.

Just register and it costs nothing.

From the 1878 marriage record it looks as though Catherine's father's name was Thady or Thaddeus.

Re Thadeus Brosnan/Brosnahan or 'Thady' as he appears on Catherine's marriage certificate in 1878.

I have often seen Brosnan spelled Brosnahan, same family name. Spelt Brosnan because the people noting the records often do not hear the 'nahan' as the h is not sounded and the voice slides a bit  like the Indian bread Naan. 

I have found a Thadeus Brosnahan leasing land in Ballybeg with relations? Hugh, Thomas and Michael Brosnahan on Griffiths Valuation. The lessor is a Richard Meredith and the four jointly own at least 190acres and more in varying family combinations. This is a sizeable amount of land for those days.

If you would like to check GV the ref is here. it was carried out in this County in 1853.

I would also search on the Irish genealogy site under parish of KILLEENTIERNA.  It has many Brosnan/Brosnahan names

I would also list the ages as she appears .....on the 1878 marriage certificate Kate Brosnan is 18 so born 1850apx. The census data found earlier will also have some dates and her death certificate will have a date.  Some where in those there will be THE date but search round those to start adding a couple of years each end to cover when in the year she was born.

Now another lead. I have just found out that Thady is a diminutive of Timothy.   So you could search for all the Timothy Brosnans or Brosnahans
