Connor, 4, and Brandon Moore, 2, shared a large white coffin which was brought into and out of the St Rose of Lima church in Midwood Park by six of Mr Moore’s co-workers at the New York department of sanitation (NYDS).
More than 200 employees of the department attended, with a guard of honour formed across from the steps of the church on Parkville Avenue as three bagpipers played.
Former Bishop of Brooklyn Guy Sansaricq celebrated Mass while consul general Noel Kilkenny sympathised on behalf of the Government, describing the tragedy as “heart-wrenching”.
“Obviously there have been a lot of victims of this storm,” Mr Kilkenny told reporters after the service. “I’ve been to Staten Island, the Rockaways, Breezy Point; there have been [older people] who have died in their homes and many other tragedies. But somehow this one has captured people. Not just in Ireland.
“The idea of two children being swept away from their mother’s arms... I don’t want to lessen the sadness and grief of the other families. But this is something truly tragic.”
A memorial service was being held at the same time in Mr Moore’s home parish of Portnoo.
