Hi Erome, and welcome to Rootschat!
Is there any chance there might be one more daughter in the family? There doesn't seem to be a whole lot of George Roome's in the records, so I thought this might be him, but he would need another daughter:

Mr. Lee, Mr. William Hall, schoolmaster, of Greenhead, Gilsland,

Dumfries.
