IFB - It's hard to say what IFB believe. Because they are independent, each church writes and/or adopts its own doctrinal statement. There are hundreds (perhaps thousands, I don't think we even begin to comprehend how many unaffiliated Baptist churches there are) of IFB churches that do hold to some form of Landmarkism. Yet, they would be a minority of the total number of IFB's.
BBF - Many of those (probably most in the South) who divided from the SBC back in the fundamentalist/modernist controversy of the 1920s would have been Landmarkers. I think the first fellowship they started was called the World Premillennial Baptpist Missionary Fellowship (now World Baptist Fellowship). The BBFI divided from that body around 1950. Even then there were still quite a few Landmarkers among them, but that has continually dwindled from that point until now. Probably most that are Landmarkers or lean toward Landmarkism left the BBFI in the recent Heartland/Global Independent Baptist Fellowship controversy/split.
GARBC - I doubt there was ever much tendency toward Landmarkism in this body, which separated from the Northern Baptists.
ABA & BMA- The ABA was formed in 1924, and is a descendant of the old General Association of Missionary Baptists, which was formed circa 1905 by churches and associations that withdrew from the SBC around 1900 (in the South, and mostly in Arkansas and Texas). The BMA separated from the ABA in 1950. This is the short version. Both groups are Landmark in outlook, but have increasingly modified their stance on this (not officially, but local churches & pastors have).
