Have you looked at the visitation given as a source in RG Horace's comment when he proposed the merge ? . https://archive.org/stream/dugdalesvisitati2dugd#page/98/mode/2up
John Hanson-531 has parents in agreement with the visitation, John Hanson-195 has no parents,
John Hanson of Woodhead did indeed marry Agnes Saville as do both these Johns.
If you look at the children: Hanson -195, has a John, and Hanson-531 has an Edward and a Thomas, the visitation agrees with this as this John (John X on the visitation) had sons including John, Edward and Thomas.
John (X1) was the heir and he had two wives 1) Margaret Woodhead and 2) Margaret Wade. Hanson-194, John the son of Hanson-195 has the same two wives.
The visitation includes the date of probate for the will of John (married to Agnes Saville) which was in 1554 with the will written in 1553 Neither of the death dates agree with this .
I think that these are the same person and should be merged. ,
edit ; the genealogy of Edward, son of John and Agnes continues on page 102 of the visitation. This is further confirmation since Edward Hanson-1518 married Joan Kaye as does the Edward of the visitation
