You need to check yourself if the information on that site is correct, I just looked at the two Margaret's and Richard's death.The Margaret baptism's are correct1806 https://registers.nli.ie/registers/vtls000633302#page/54/mode/1up right hand page1809 https://registers.nli.ie/registers/vtls000633303#page/9/mode/1up left hand page1873 death of Richard gives his age as 60https://civilrecords.irishgenealogy.ie/churchrecords/images/deaths_returns/deaths_1873/020697/7261638.pdf (you need to sign in and prove your not a robot) which if the age is correct would give him a later birth year, death ages are often incorrect. The quality of the image is terrible, not sure who the informant was.Lot more checks needed on the information from that site.
