"the note about the poor law union district, Does that mean that they might be mentioned on the records or that they were at some point in the poor/work house."No. Ireland was divided into Poor Law Unions which each had its own Workhouse but when civil registration started these Poor Law Unions formed the basis of the registration districts. To search for details on townlands in Ireland (civil parish, poor law union, etc.) see

Word of warning- registration districts divided into sub-districts which are sometimes listed in LDS database (
www.familysearch.org).
Thus, when searching for the Kelly children (presuming all born at Shandrim) the civil index should be Inishowen.
Here's a few possible births to start with-
Rose Anne Jan./Mar.1888 Inishowen volume 2 page 122
Joseph Jan./Mar.1892 Inishowen volume 2 page 105
Owen Jan./Mar.1894 Inishowen volume 2 page 117
Sarah Oct./Dec.1897 Inishowen volume 2 page 103
George Apr./June 1903 Inishowen volume 2 page 109
This looks like the parents' marriage:
William Kelly Jan./Mar.1887 Inishowen volume 2 page 159- Margaret Doherty on same page.
