Scatty -
Your reply is full of detailed information. Am unable to find what you quote as the church records site - do you mean irishgenealogy.ie - civil registrations?
I hope PollyB is still reading here and sees your great find.
From the civil registrations I could see what you found,
Birth of FLORENCE MARTIN on 28 March 1910
Group Registration ID 825819
SR District/Reg Area Dundalk
Sex Female
Mother's Birth Surname COURTNEY
Also the marriage
Party 1 Name JOSEPH MARTIN
Party 2 Name ANNIE COURTNEY
Date of Event 03 February 1910
Group Registration ID 2012755
SR District/Reg Area Dundalk
At irishgenealogy.ie in the civil registrations it does have the IMAGE to see the civil record and it gives Annie's father as John Courtney, deceased, blacksmith and sure seems Scatty has found PollyB's family.
