I think 3 minutes googling is enough to decide that Lucy's DOB is perhaps less on line than... Although Neil Patrick and the girl that played "Wanda" were born in 73 and 72 respectively, and all the kids on Doogie hause, their characters were supposed to be 16 in the pilot, and were supposed to all b the same age... The guy that played "Vinnie" was born in "1967". Thyroid condition?
So Mulgrew born in '55 could have easily been Lucy Boryers mother, and equally so Ensign Janeway could have easily been Captain Janeways daughter.
What would that say about Kathryn, if she had a daughter back home that she refused to talk about or acknowledge?
