Thanks to Janine I now know that the Rosanna Petrie I was looking for in sillardyke, Burray was born c 1858 to William Petrie and Christina Ross and known as Ann. William must have died soon after as in the 1861 census Ann Petrie aged 3 is living with her grandmother Christina Ross. In the 1871 census she is still at Sillardyke listed as step daughter of James Bruce, farmer and Christina, wife Also her siblings Jemima Bruce b c 1866, John Bruce bc 1867 and Jane Bruce b1871 Christina Ross her grandmother is still alive and staying with them. She is 81 and listed as born in Stroma, Caithness Ring any bells Kay
