Your source is not great, because it basically uses name matching, and as I've already pointed out by noting the Pope named Mercury, there are an awful lot of early Christians who were named after pagan gods and goddesses. If they become saints, then, yes, their names move across, but then you need to prove that they have something to do with each other in terms of actual continuation of belief. Also, some of it is just, well, clearly wrong. To grab two easy examples:
St Martin in the Fields isn't named after Mars. I'd note that its sister church is called "St Giles in the Fields", so the idea that it's named after a field god is off. It was built under Henry VIII, so any idea that it's a Roman survival is a bit tricky to prove, and the guy it's named after, Saint Martin of Tours, is one of the few who has a contemporary hagriographer (that is, his biography was written while he was alive, by someone who, in this case, knew him personally.) That Martin, a first-generation convert in a military family, was named for the war god of his father is not at all strange: it was a really popular name in Roman military families. The idea that he is Mars in a Christian form is weakened by the fact that the reason he's a saint was that he was a conscientious objector to military service who forsook it for contemplation. Also, he was famous for destroying a pagan temple.
St Lawrence isn't named after the Lares. The first strike against it is the transliteration only makes sense in English and requires depluralisation and a vowel change, because Saint Lawrence Beyond the Wall is in Rome, where it is called "San Lorenzo" so the idea that he's a lar is harder to sell. The second is that the Lares were not field gods, they were locational gods, including household gods, so being defined as "outside the wall" is precisely the opposite of what they do, control a defined space. The third is that we know that the site was not a temple in Roman times (it was a place of execution outside the walls of Rome). The current San Lorenzo was built in the 13th century, on the site of an earlier church, which was in turn probably built on the site of an oratory, so the idea of continuing practice is a bit weak. The fourth is that it seems not to argue continuing practice that the he's the Patron Saint of Librarianship and Cookery (were I Catholic, Lawrence would be my patron, if I weren't trying to squeeze a miracle out of someone else to get the up to sainthood).
Also: Saint Nicholas is still a Catholic saint. I'm not sure how he can have pagan antecedents when the stories about him seem medieval in origin, unless you accept some sort of conspiracy theory regarding pagan survivals. Yes, he name has "Nike" in it. This no more makes him the goddess Nike than my name having God in it makes me God (The -thy in Timothy is "theos", which is "God"). In Nick's case, the other problem is that nike is an adjective so it turns up everywhere (in his case his name means "victory of the people") I'm not sure how you see a continuation of practice between a goddess of athletics and war and a guy who is basically a charity god.
