I am looking for any information on Catherines children or parents.

Question

I believe Catherine's maiden name is Mc Glynn. They had seven children according to the 1880 United States Census . Catherine's parents were born in Ireland. Her brothers Edward Mc Glynn and Manus Mc Glynn were living with them at the time of the 1880 census in Brooklyn , Kings, New York

Curious why you have NZ links on your profile for Mary Houston who you say was in NY.

Yes, I think that you have the wrong profile linked in your question.
if you check out the cemetery(Makaraka) that the profile metions , it is inNew Zealand. You can find a picture of  her grave.
Her married name was Graham, her maiden name was Houston. I'll try to put the link but it may not work http://www.gdc.govt.nz/online-cemetery-record-search/detail/35503?backLink=%2Fonline-cemetery-record-search%2FForm%3FNotHelpulInfoReason%3D%26LastName%3DGraham%26FirstName%3DMary%26action_find%3DSearch
