I regret that this thread continues though a conclusive DNA test was done with Mr Searle and Mr Henry Lengefeld Jr. These two men were found to have absolutely different Y chromosomes. In DNA testing that is as sure as it gets that two males are not of the same father.
It is unfortunate that Ms Searle pursued her fantasy of a father for her children from a "Texas rancher" and her family had visions of wealth. Their unrelenting pressure trying to prove a lie caused Henry Lengefeld pain and reduced stature in his family and has caused his wife and family anguish as they have portrayed Mr Lengefeld as a deserter of a son. That has been found to be a lie proven with absolute certainty by Y chromosome DNA test that came too late for Mr Lengefeld who passed in 1967 after a lifetime of falsely be accused. The truth is that Ms Searle had many many lovers and it is apparent that one of those lovers were the father or fathers of her children.
