I am wondering if someone could help me please with a lookup for a William Patrick Corcoran, born between approx 1828-1832 in Dublin. Parents names Edward Corcoran and Ann Nugent. I am wondering if there was a marriage between him and a Rachel Fitzsimons in Ireland sometime before approx 1857.

I think there were two children the marriage, Francis John and William Edward.

William Patrick Corcoran emigrated to Australia approx 1857 and had two further marriages, to Mary Ann Burns McGonigal and Margaret O'Connor.
