Lennon's and McGee family

I am a descendant of William and Margaret LENNON (nee MCGEE) who were married in the Portaferry Catholic church in the 1852.  Thomas CONVERY and Ann LENNON and had 6 children baptised there.  In 1870 they migrated to Melbourne, in Aust.  Margaret arrived in 1981 with her 6 children and on board was a Peggy MCGEE and her 2 children.  I presume they were sisters in law.  William prob arrived a year or 2 before.

William's father was listed as a William too on his death certificate while Margaret's parents were called James and Margaret MCGEE.

I would love to make contact with either descendants of these 2 families anywhere in the world but particularly still living in the area
