I'm not sure how this profile ranks as a Master Profile.Most of the time, Master Profiles are legit. For one's like this, however, one may rightly ask, "Is it up to others to struggle ad find source to validate MP profiles without sources?
The information in Overview shows no source..Nothing in the Sources tab is a source of merit. Yes, there are a lot of trees connected to this profile. However,.Many trees' data alone does not alone a valid profile make.GEDCOM uploads carry the same errata or lack of sources from their origins
It’s right to be skeptical about this lady, her maiden name is not verified.
I’ve added these notes to profiles and will do some cleanup.

It may be supposed that John Fuller was born about 1510 probably in Redenhall Parish, County Norfolk, England. His father is thought to have been William Fuller, but the name of his mother is entirely unknown. Even so, it is likely that he married about 1533 or, perhaps, a year or two earlier. Moreover, it has been commonly stated by family researchers that his wife was Ann Collinge, an assertion which seems to derive from a reference to "mother Collinge" in the will of his son, John.1 However, there are other plausible explanations for this usage and the conclusion that Collinge was the maiden name of John Fuller's wife does not seem particularly convincing. Alternatively, it has been suggested that the wife of John Fuller was Ann Hoptkins and that his mother was Ann Collinge, i.e., she was the wife of William Fuller. However, there seems to be no documentary support for either of these presumptions, hence, both should be disregarded. Apparently, John Fuller died in April or very early May of 1559 since his burial on May 3, 1559, was recorded in the register of Redenhall Parish. (Alternatively, it has also been reported that he was buried in the Choir of Jesus College, presumably at Cambridge University, but this seems hardly likely.) Moreover, he had made his will three months earlier on February 4, 1558 (1559 N. S.) in which he made bequests to two sons, John and Robert; a daughter, Ales (or Alice); and probably two minor grandchildren, Stephen and Frances Sadd.2 Within this context, it has been frequently reported that of the two sons, Robert was older that John. However, John was left all of the property and instructed to pay his brother ten pounds. This is a clear indication that he was the oldest living son, since the custom of primogeniture prevailed in England at that time. In addition, John was made sole executor of his father's will further implying that he was of age, i.e., twenty-one years of age or older. In contrast, it would seem that Robert was younger than twenty-one years in 1559, perhaps, about sixteen.
