Downes Family- 1800's

[tubbs]

Looking for any info about the Downes Family who possibly lived in Mullingar or Ballinagall in the 1800's.
Parents were Myles Downes & Bridget Martin. Three sons came to Australia & 2 sons went to the USA. Not sure of any other children.

Children I know of are

John b.1837-
Myles b.1835 married Elizabeth Cavendish
James b.1845

Patrick b.1846/1850 - USA
Michael b.?- USA

Any help appreciated,
cheers
