Hi Helen thanks for all the info. In 1881 Elizabeth Ann age 12 is living with her aunt Mary, her mothers sister, and her husband Joseph Fulton in Lisburn Terrace Bishopwearmouth, Durham, England She is listed as a neice with the surname Irwin, picking up her mums new surname,so all that really fits. Joseph Fulton was later a witness at Elizabeths wedding to John Robert Robinson in Grimsby in 1890. This is the family I am researching. Maybe she wasnt Wilsons child, I dont think I will ever know, I just thought it strange she appeared to pick up her mums new name if only for a while, because Elizabeth was married as a Chambers!
Thanks again, as I replied earlier I have written to the guy who manages the Orwin website though I dont hold a lot of hope as the Orwin page hasnt been updated for a few years.
Thanks Tony
