Yes

and what did I get? No Thomas, but the rest of the Gaffigan Clan. Patrick, Mary, and John showed up in the 1861 census registration.

I ran it with the ages, rather than by name, as in John, eliminating everything but ages 1 through 3 on the census information. I did that for each group (still no Thomas) using your asterisk's.
Using your asterisk would cost a bundle, which I do not have, were I to track each and every one that came up. For example, for John there were 263 hits in 4 categories. For Thomas, 133 in 4 categories and Thomas became a hit this time. But it wasn't anything different for the family unit.
Although it was a wild goose chase - IN THIS INSTANCE - it is a way to cross reference and look at those things that are so far away, and ancient, it should be done if you are not confident that something else will pop-up.
