Hi Tanya,
I think you might be referring to my great-great-great-great-grandparents, William Roser & Dianah Wilson, who immigrated to Australia about 1842? They bore 8 children in total; Lucy, Elizabeth, Fanny, Mary Ann, Diana, William John, Caroline, & James.
Their daughter Lucy, is my great-great-great-grandmother. She married a John Charles Playle 28th Dec 1849 in Northam, Western Australia. She died 13th Sep 1913 in Northam, Western Australia.
Most of the Rosers/Playles settled in Northam & Toodyay in Western Australia. I have a few photos of headstones from the Northam Cemetery I'm happy to share with you, but I've attached a photo of Lucy Roser & John Charles Playle for you.
I've only just started branching out more on the Rosers/Playles, so I don't have alot of info, but I would be glad to help in any way that I can.
Regards,
Rachael
