hi
could you post a close up version of the attached photo so that people maybe able to assist you identify where Bridget was from. There is no place called Yokalshan in Tipperary that I am aware of.
There are no births for a Bridget parents Thomas and Margaret for 1857.
Between 1847 and 1867 there is only one Bridget registered to parents of that name- Bridget baptised in Templederry in 1862
kind regards
Margaret
