Looking for Bennetts and Kenny from Cavan Ireland area

We went to Ireland this lasy May.

Couldnt find out anything new.

We have good information on the Bennett family from 1822 forward.

This is when the Kenny's and Bennett's left the Cavan Fermanaugh area and sailed to Canada.

I was given information from another relative of a 1821 census where they were still living in

Drumhecknagh, Kilmore Parish, County Cavan, Ireland

The census lists Edward, Julia and children living in one house.

A Mary Bennett living in a house next door with 2 younger children. Its said she is widowed.

It was believed this was Edwards mother.

It indicates in 1821 that Edward was 23 years old yet the children living with Mary Bennett were 11 and 14.

It was said Mary Bennet and the 2 younger did not travek to Canada bit stayed in Ireland.

Then the father of Julia, Noble Kenny lived with his family in a 3rd house.

Edward was born in 1798, Julia was born in 1800.

I so far have found no information on Edwards father or if Mary was the mother.

We have found nothing prior to that 1821 census.
