Can someone PLEASE help me.

My name is Mary Hood, (nee Lugg) I would greatly appreciate it if someone canhelp me find anything about my paternal grandmother.

Believe she was born in Dromtarriff to Daniel Collins and Hanora Cotter,is said to have a brother Dennis and possibly 2 sisters

She married my grandfather John Lugg in 1882at Mt Barker South Aust and they then lived in Nairne Sth 

Aust. She died in Adelaide in 1934.

I  have spent many hours trying to find out anything and I had given up, but curiosity got the better of me. I now live in hope that someone out there can help me .  Mary
