Looking for Lascalles

I have a Mary Lascalles who married a John Coombe in Exeter, Devon, England on 5/9/1814 and their son is George Coombe married to Margaret Dee on 9/11/1857 in Sydney.
Any Lascalles relatives?????
Our family has carried on the Lascalles name as a middle Christian name e.g.Ray La Selle ___
