Not sure about that, there should have been about 50 if so and from the readme provided by the census "To safeguard privacy, we restrict our list of names to those with at least 5 occurrences."

    usa$ grep -i bacon yob????.txt | wc
           0       0       0

Shouldn't your search also find the 29,000 people with the last name of Bacon? https://www.wolframalpha.com/input/?i=bacon&a=*C.bacon-_*Sur...

No, it does not include that:

    usa$ head -5 yob2008.txt 
    Emma,F,18791
    Isabella,F,18598
    Emily,F,17419
    Olivia,F,17066
    Ava,F,17024

The USA Census Bureau released names.zip and namesbystate.zip back in May and they include README files of how they were anonymized.

Maybe some of them as a tribute to Francis Bacon?

Yeah, who'm I kidding...
