I tried searching for the Donnelly's in Ireland, but I needed a place of birth for them. I picked Tessie (Teresa) and tried to see if I could find out where she was born. I know from your records that she married Arthur Krulish, so that helped a little bit, because I know that she was living in New York.
I think that when Arthur died, Teresa reverted to the name Donellan, because I found a Teresa Donnellan, b 1887, aged 69, departing New York and arriving at Southampton on 17th July 1957. She was on the MAURETANIA, she was a typist, and the address she was going to was: C/o American Express, London.
The ships passenger list said she intended staying 1 month.
However, I found that a Teresa Donnellan aged 70, b 1888, had died at Carrick-on-Shannon, Co Leitrim, Ireland in 1958, and this made me wonder if Teresa had taken unwell while in the UK and had gone to Ireland.
Because she died at Carrick on Shannon, I tried to find out if a Teresa Donnellan was born there around 1888.
Surprisingly, a Teresa Donnelly was born 1st qu 1888 at Carrick-on-Shannon. Vol 3 Page 55.
It could be that the Donnellans came from there, and you may be able to get proof, perhaps. I didn't see anything for Martin and Bridget.
Do you know if Teresa was a typist? If she was, then it is more than likely to be her who made the voyage on the MAURETANIA above.
