Sara Allgood date of birth

The date of birth for Sara Allgood (https://www.imdb.com/name/nm0021329/) is incorrect. The Irish genealogy site is pretty thorough but there are mistakes and this woman has been credited with no fewer than three different dates of birth. The correct date is October 30, 1880 (the year 1879 on her gravestone is incorrect). She could not have been born November 29, 1880 as she was baptized on November 3, 1880.  The baptismal record (digitized hand-written original document and summary are available and accessible without fee or paywall or subscription    https://churchrecords.irishgenealogy.ie/churchrecords/details/51393a0198879?b=https%3A%2F%2Fchurchrecords.irishgenealogy.ie%2Fchurchrecords%2Fsearch.jsp%3Fnamefm%3DSarah%2BEllen%2B%26namel%3DAllgood%26location%3DDublin%26yyfrom%3D%26yyto%3D%26submit%3DSearch https://churchrecords.irishgenealogy.ie/churchrecords/display-pdf.jsp?pdfName=st.marys_pro-cathedral_mf_1880-1889_ba_0113 Please review.
