Yes, it does but there is some confusion here. The names of the mothers of both are, in one instance illegible, and in the other different from the names of the mothers on both John and Catherine's death certificates.
On the marriage certificate John's parents are given as John Kelly and what looks like Mary something. Catherine's parents are given as Patrick Mackay and Margaret Smith. However, on John's death certificate his mother's name is given as Ann Madden-same name as before for father. On Catherine's death certificate her mother's name is given as Margaret McAndrew and, again, same name as before for her father.
I have tried LDS for a match up of all of the above but no luck. However, LDS was able to provide the names and dates of birth for all of John & Catherine's children which was brilliant. However, only my grandfather and one of his brothers survived. All of the other children died either in infancy or in their teens. Tragic.
Hope this isn't a case of giving you "too much information". Don't wish to bore you.
Best wishes.
