Thanks again to our wonderful volunteers we now have 658,041 index records from 67,266 memorials of deeds in our main database. This and all other databases are fully searchable at:https://irishdeedsindex.net/search/search.php
The highlighted memorial is https://irishdeedsindex.net/mem.php?memorial=187015289 that is a marriage settlement from 1870. We can compare the information in the civil registration record https://www.irishgenealogy.ie/files/civil/marriage_returns/marriages_1870/11384/8179875.pdf
Together they give fuller information about the marriage. The civil registration record provides names of fathers of both the bride and groom whereas the memorial gives the name of the bride's mother. The deed was executed on 21 May and the ceremony was performed on 25 May. Baron Farnham signed the civil register with his title name and was a trustee of the marriage settlement.
It is always nice to have more than one source for information about people you are researching.
