The March issue of Starlog magazine, #363, has an interview with
Samantha Eggar. Of course she talks about playing Marie Picard in TNG
but she also mentions Kate. Here's that part:

Starlog Magazine - March #363

Next Generation wasn't her only Star Trek connection. "I did a movie
called Round Numbers with Kate Mulgrew from Star Trek:Voyager," Eggar
says. "She became my best girl friend after we met on that. It was a
great story, but it didn't turn out terribly well or hugely
successful. Still, what's great about doing these projects are the
deep and lasting relationships that you form. The woman who made Round
Numbers mortgaged her house to do it

"Kate and I were having lunch in Brentwood one day, and Kate had gone
on an audition that she said was terrible, and her marriage at the
time wasn't in great shape. She wasn't really happy. About a week
later, Kate got the role as Captain Janeway and soared to stardom. It
was so wonderful that someone who was emotionally downhill could turn
it around and be given this extraordinary job. Kate is such a pro, and
she nailed it. She is a dedicated, hard-working, serious, highly
intelligent, amusing and flat-out brilliant friend."
