Yes, her family did settle in St. Paul (Frogtown neighborhood), and I see a Saiko listed in my coworker's family tree. I will forward your name and email address to her. I'd love to send you what she has, but she's kind of skittish about sending it to someone she doesn't know on the internet. (Though I've mentioned that here at Rootsweb, we're just a bunch of genealogy nerds who can't imagine using this info for nefarious purposes.)
With my own family research, I've had such a fabulous experience exchanging info with other family members. I'd be so stuck without Rootsweb.
