Pilkington - Lowe marriages in Co Westmeath, Ireland

A well to do Pilkington family lived in southern County Westmeath, Ireland, in the 17th through 19th centuries.They were gentry.Tney intermarried with a Low/ Lowe family that lived nearby.The place was near Tyrrellspass, near the southern county line.

I need dates on these marriages, if anyone has genealogical information on this family.Landed Gentry is weak on the dates.

Yours,
Dora Smith
