Contact la leche league. Tell the leader you are trying to find a homebirth MW. If she doesnt know, she might know someone who might know. I was given one number, that lady gave me another number, that lady gave me another. I had a scratch pad filled with names and numbers when I was done. 6 degrees of seperation right? I found one! Im sure you can too!
My MW isn't listed anywhere. I found her by asking in my tribal area (one person had a birth attended by her before and emailed me), and then got another reference to her through a LLL which is 45 miles from here. It took a couple weeks last summer to get her information.
