Bridget McCarthy c1830s to 1918 Australia

According to Mahoonagh parish records Bridget McCarthy married Michael Scanlan Feb 21st 1854

The couple lived in Killeedy (Killeedy North) raising a family.
Michael Maria Helen Margaret Tim & Patrick.

We think family fell on hard times and forced to emigrate

but after 1863 the emigrated to NSW Australia..

I matched with
Patrick's grandson in Sydney
Any info about either Michael Scanlan or Bridget McC would be great.
Did whole family go?
we know Tim & Patrick did... we think parents did also..

any info would be great

kind regards Pat Scanlan
