Barnane//Barnett and Donovan

I'm not sure how this website works but I will just my information out and see what happens.

I am looking for information on Florence Barnane/Barnett who married Mary Donovan.  The family lived in the Downeen area of Rosscarbery, County Cork.   Mary was born approximately 1840 - 1845.  Her death certificate says her father was Denis; however, I have found a marriage certificate for a Florence and Mary where it states her father was Timothy.  It's possible this is not the same Mary and Florence, but everything else fits.  I've given up on finding anything else about Florence Barnett but, what I would dearly love to learn is who Mary's parents were and the names of any of her siblings.

Mary and Florence had a number of children, starting December 1868 and I have the names of all but three of them.  Her children were not to have very long lives, as in 1910, only four were living and by 1923, only one was living.  In 1903, she emigrated to Boston, USA with three of her children, Nora, John and Katherine. One was deceased and another was living in Boston at the time.  That leaves five children that I cannot find anything on after their baptism--the three names I don't have and Daniel and Florence.

Thanks
