Have you tried looking at church records for more information? Most Catholic records are held locally so you may need to write to the local parish priest for possible assistance. One website that you may find useful is the Irish Times where they give an overview of what records are available in specific parishes. It also shows you where copies of the records are available. For Kilfree/Gurteen parish, follow this link:
As you can see from the above links Sligo Heritage and Genealogical Centre have copies available. If you would like to contact them here is their email, however a fee may apply:
You could also try searching at:
www.familysearch.org has a huge database of genealogical records including some church records for Ireland.
www.rootsireland.ie have a large collection of Irish Church records, however you have to pay to use this site.

Griffith?s Valuation (1848-64) numerous Dyers recorded in Kilfree including a Hugh and Patrick:
Hugh Dyer was also recorded in Kilcolman:
Civil registration began in Ireland in 1864 so any births, deaths or marriages in the family after this date would be recorded in these records. Civil records are available from the General Register?s Office. Here is their website:
You can search the indexes to these records up to 1958 online at:
You could also check if there were any Dyers still in the area in the 1901/1911 census records here:
