the revised numbers are not the same person, they are different 1st names.
- [[Gray-6151|John Gray (1542-aft.1602)]]
- [[Grey-136|Thomas Grey (abt.1526-1555)]]
Doing a search for John, as well as Thomas. I didn't find another profile with similar dates,
There is a rejected match between Gray-6150 and Grey-136, which is what your question was about, but Gray-6150 and Grey-136 have very different dates.
[[Gray-6150|Thomas Gray (abt.1510-)]]
