Hello Lyn,
my best suggestion would be Beatrice Ann Crosby in the December quarter 1899, Gateshead;10a 934. The Crosbie family had no links to Sculcoates, but did have to the Gateshead area. In 1891, John Crosbie was living with his cousin Henry Walton at Victoria Garesfield, just west of Rowlands Gill in the Gateshead registration district.
Not sure when I shall be in the north-east of England, but it should be before Christmas (my father lives in the region), and I will have a look at local baptisms in the Tyne and Wear Archives for Beatrice. It may be a long shot, but buying English certificates is an expensive way of being wrong.
If you send a private message with your e-mail address, I will send a gedcom or report with the details of the Crosbie family.
Regards,
John
