Trying to find documentation of the birth on 10 August 1884 of Sarah Helena Boulger in Kings County.
I found this document years ago but cannot locate it again. Although I'm not certain of this, it might have been a Roman Catholic church record.
Her parents, William Boulger and Eliza Byrne were both born in Co Wicklow and are listed on the document.
There is a Sarah Boulger born in September, 1875 in Co Kildare (Naas) that could be her, but the date of 10 August doesn't fit nor does the location.
Any guidance to help locate the Kings County (Offaly) document would be most appreciated. I've searched all of the typical sources, to no avail.
