I'm sorry, I don't know of any homebirth midwives in the area. Some women in Manhattan do drive to the Topeka Birth & Women's Center, though. It's a wonderful freestanding birth center, and as close to a homebirth as you can get without actually being at home. I had both of my kids there. It's about an hour (maybe a little less) from Manhattan.
I don't know of any midwives in Manhattan, but there are some in that general area. The Birth Partners website would be a great place to look. If she can't find a good option closer, I'd consider taking her, though I'm 2-2.5 hours away, so it wouldn't be an ideal situation.
