I found on familysearch.org 4 marriages for Thomas Moloney in co Clare.They are; 1876 Scarriff 1877 Ennis Jan-March 1878 Kilrush Jan-March 1881 Scarriff The only thing is none list the bride's name.
I also found this marriage record of a marriage which took place in Feakle which could be the people you seek.
29 February 1876 Feakle parish Thomas Molony and Mary O'Connor married witnesses;James Hanrahan/Catherine McMahon priest:Joseph Meade
If it turns out that the above are your family I also located 3 baptisms for this couples children which may be a few of the missing children.
Feakle RC parish baptism records:
24 Jan 1876Michael parents;Thomas Morony Mary O'Connor sponsors;Michael and Anne McMahon priest;J.Meade
9 April 1877 Mary parents;Thomas Molony Mary O'Connor sponsor;Mary Molony priest;J.Meade
28 July 1878 Mary parents;Thomas Molony Mary O'Connor sponsor;Bridget Molony priest;J.Meade
The problem at the moment is that co Clare records have yet to come online.If I come across anything else I will let you know.Hope this helps,Kim
