Bobbie, I finally noticed that the person who oversees Howland descendants for Mayflower Society (and is editor who revised the MS publication cited in error on some profiles) actually posted in Comments on the profile three years ago confirming the correct children for this Samuel and Esther (vs a fourth cousin with the same name, same wife given name and same father given name--no wonder there was confusion). The children she lists are in line with NEHGR. Given this, I think disconnection of the errant children should go ahead (with the usual notices on profiles) if the PMs do not make the changes within reasonable time (the PM has not been active since 2017).
Edit: the work improperly cited is Soule, John E., and Terry, Milton E. “George Soule of the Mayflower and his Descendants in the Fifth and Sixth Generations.” Mayflower Families in Progress, revised by Louise Walsh Throop [our Commenter on the Howland-1172 profile], First Edition: Part three (Family numbers 465-551), General Society of Mayflower Descendants, 2003 pp. 159-160
Edit 2: It would appear the 4th cousin of the subject Samuel Howland of the same name with a father Samuel and wife Esther is not presently found in WikiTree. The profiles of those with the same name born within +/- 12 years of the subject Samuel are Howland-4291 (1c1x); -3233 (2c); -907 (2c1x); and -3473 (2c1x). I don't see anyone who is a probable match using the +/- 30 year parameter. Or, we have an additional error in WT in the family.
