Concerned about timeline on the name choices

[phoenixglass.livejournal.com]

I've been working on a collaboration novel with a friend, and I get to name and design half of the characters that our story will need. The nature of it requires the characters to be from different time periods (within reason, no time travel involved) and so I had done my best to pick out some names that would be commonly used in the times they were born in.
So I'm kind of hoping that in addition to critiquing the choices, that I could have some help with making sure that they were names that wouldn't be out of place for the time they were born.

Angelica Beauregard. - born in 1983 - french on her father's side

Bernard Smith. - Born in 1922  - want to keep this one simple

Alice Carroll. - born on the last day of 1999, has a Taiwanese maternal grandmother, so maybe the name is not a good choice?

Esperanza. - born in 1994, she's homeless, so she has no last name that she remembers

Tabitha-Storm Wilder. - born in 1995. I want her to have kind of a ridiculous name that she hates, so hence the odd choice

Christopher Sageull. - born in 1979

Erik Yohanson. - born in 1973

Do the names sound plausible for the times chosen? Or plausible at all indeed?
