Julia Connell (Stage Singer born in Duagh Parish)

I'm looking for any information about one Julia Connell. She was born in the townland of Ballynagraigue in the parish of Duagh in 1872. Her parents were Philip Connell and Catherine Meade. The only other thing I know is that she emigrated to the USA and became a singer. I've been told that she was a well-known singer in her day. Specifically I was told that she sang on stage - whether music hall or opera, I don't know. It's said that she never married. She had a younger sister Bridget who I think also emigrated to USA in 1905. No one in Ireland knows anything more about them. Julia did have her portrait painted at some point. And my third cousin has a photograph of this hanging in his house. But he knows nothing more about her.

If anyone knows any resources where one might track stage singers from the late nineteenth or early twentieth centurries, please let me know. Thank you.
