Hannan, Oldfield 1840 – 1880

My Gx3 Grandparents were James Edward Oldfield and Margaret Hannan. I know that James was born in Windsor in 1821, son of James Oldfield & Ann Nancy Henshaw nee Freebody. He and Margaret Hannan (age 16) were married in Tambaroora in 1854, by Fr Kums. I’ve recently discovered that Margaret’s parents were James Hannan & Mary Clancy. They were from Co Clare, Ireland. They had another 7 children after arriving in 1840. James in buried (1874) in Wattle Flat RC Cemetery. Mary died in Molong in 1880, but can’t find her burial. Can you give me any information about them? Gail
