im well and truly stuck

my gg grandmother was born louisa Kirchner / kirchener / kitchener / kischener in limerick, ireland
ive got her wedding certificate which shows her fathers name as benjamin
ive found her in all the censuses and the death record but cant find her birth anywhere and cant find her fathers either
ive tried different sites and the Irish parish records and the applotments and the Griffiths list to no avail
if i send off for a copy of her death certificate how much detail will be on it in 1901 - will there be birth and parents details or does it depend on the coroner or who reported the death
thanks for any help
