BOYLAN - Cloonoose, Ballyhealan

[oisin7571]

Trying to trace ancestry of Owen Boylan (my g grandfather) born Cloonoose, Ballyhealan (born date unknown, died approx 1941-1945).
I found listings for  James Boylan and Thomas Boylan of Cloonoose in the Griffiths Valuation of 1856 but unsure whether they are related to me. Apart from that have hit a brick wall.
From talking to relatives I know we are related to O'Reilly's, Brady's, Wilson's and Maguires (somehow) but understand that these surnames are of numerous occurence in the area!!
If anyone can find any birth, marriage or death records related to Owen Boylan it would be of great interest to me!!
Many thanks in advance for any help.
Regards
Sarah
