It does not sound like her. I have her marriage cert' from Edinburgh and she states her father was Thomas Arthur Corlett. I also found her on the 1871 census living in Edinburgh age 10 with Thomas A and Matilda(Watterson). The census said Catherine was born in England but I haven't found her yet. As Thomas A and Matilda do not seem to have ever married I assume she was illegitimate. Thanks for your information.
