If anyone is interested, as recommended by garstonite I contacted Old Mersey Times. Jane found the following article in the Liverpool Daily Post, four days after the original article:
"In the Daily Post of Monday last there appeared a paragraph stating that a girl nine years of age, named Matilda Richardson, the daughter of a compositor in this establishment, who resides at 55, Minto-street, Kensington, had not been seen by any of her friends after she left St. Jude’s School, Low Hill, on the previous Wednesday afternoon. The girl is still missing, nor has any clue been obtained as to what has become of her. Her age precludes the idea that she may have been taken away and detained for any worse purpose than that of begging or contributing in some other way to the interest of vagabond life. In the hope that some information may be obtained which may lead to her discovery, we repeat the description of her. She is rather tall for her age, and is light complexioned. When she left school she had on a brown straw hat, a black and white dress, a light-coloured jacket and laced-up boots."
No other evidence of her in England or Ireland can be found.
