I voted 11 or more - I am only counting women who I really know, can list them by name, I know I have met many more but my total off the top of my head including myself is
18 and all but 2 of them live in my same city

ETA: We all give each other support of the 18 homebirthers that I know I see 8+ on a regular basis. The first homebirther I met was about 10 years ago in a Bible study. I had my first two children in the hospital sans epidural. The fact that she was a HBer came up because another woman in the group had a SIL that was planning a HB and this woman was very upset about it. The homebiring Mama spoke up and that planted the seed. It wasn't for another 5-6 years before I was planning another birth and I called her even though I had not seen or spoken to her in years. She recommended the MW I ended up choosing

When I had #4 one of my fellow HB friends was here as my support person for my children. We recently had a blessingway for that Mama and I will soon be the support person for her children in this birth expected very soon.
It is so nice for me to have my own community of homebirthers that I can share experiences with and have suport me - I am very fortunate!
