Hello everyone and thank you for your help.
This is the marriage info of my great great gparents but I can barely read the details which may be very helpful as this is where I am completely stuck.  Can anyone tell me where/how I could get
a clear copy of this document?  It is from St Agathas in Dublin.  I have tried emailing them multiple times but no answer.  I have tried reporting the image to ancestry multiple times but no answer.  Can I send away for a copy somehow?  
Thanks!
Julie
