Searching for Denis Prenderville and Family

Hi I am searching for Denis Prenderville who was a draper married to Mary Griffen . Denis is listed on the Primary Valuation of Tenements for Parish of Castleisland. I also believe they were from Tralee as well. I am descended from their daughter Elizabeth born about 1801 in Tralee. Elizabeth and her husband Thomas Lovat and their family sailed on the Lady McNaughton 26/02/1837 bound for Sydney Australia.

Thank you for your help
