The Ponsonby family in Kerry, lived in the Kilflynn area.
This is about six miles from Tralee, the capital.
If you have not done so already, it might be worth a look
at the Mormon site on line for Ponsonby records.www.familysearch.org
has many records for the family,
including some from the Kerry area.
Someone has already done the pedigree chart, for the family,
and I think it is available on CD rom.
You can find out how to obtain it from the Mormon site on
You may find your Ponsonby line in there.
The family does include Lords and Ladies, and there are
many connections to follow, including some marriages with
the Blennerhassett family too.
