Note: If you wish to guarantee the largest possible village, download a "Tyken's Test World" (Like this)(lowgrass recommended for Norman villages, sand for Hindi). These worlds contain 500x500x100 or so flat area for building (so no "no room" error because of elevation issues). It is also "unchunked" meaning that you can explore it and have a village appear in the premade area. Supplies are in the base in the center/spawn, as you will rarely find supplies inside the 250,000 square foot plot of land. Or you can use a village wand on a giant flat area you carved out yourself. The easiest way to do this is using McEdit simply fill in an ocean with grass. (If you're not so "into" playing on a barren flat world of nothing)
If you need to get in contact with someone regarding village types, please try the Discussion section as your first port of call. If no-one can answer your question there, send an email to the section admin.
