I have more Irish ancestors that I hope some one can look up for me.

David McIntosh b.c 1848 in Londonderry, Ire. according to his marriage cert.

He came to Australia some time before 1876. His parents are given as John McIntosh, a farmer and Martha Lindsay.

David married in Australia and his wife was also from Ireland. I have only the following info on her.

Mary Gilmore b c 1850 in Londonderry Ire. From marriage cert, her parents were Patrick Gilmore and Mary Dinsey .

Mary came to Australia as an assisted immigrant in 1868/9 on ship 'Corona'.

Any info appreciated, thank you.
