To my eyes the name looks more like Law on the rest of the document that seems to mention William Law and Ethel Winterton.
Is the entry about Thomas Lea about another entry on the page and has slipped down because the priest has run out of room?
The Latin annotation here is added to the baptism entry of Edith Ethelreda Richmond, Leicester, 1906. She married Edward Lea in Leicester in 1929 (as per annotation, except that it mistakenly gives his name as Thomas Lea, which - coincidentally? - was the name Edward’s father. (Or maybe the document from which this annotation was produced named Thomas as father, and the wrong name was copied down?)
The names on the baptism, William Law and Ethel Winterton, are probably the names of Ethel Richmond’s godparents, who I think are normally named on R.C. baptism records.

Added: just checked the baptism and Googled, and those names (“patrinus fuit” and “matrina fuit”) are definitely godparents. Also Ethel’s mother was Rose “olim” or formerly, Law. So William Law must have been related to Ethel’s mother.
