Johannes Quackenbosch - Needs repair

I disconnected a gedcom which has brought the siblings right down, I can't isolate it for some reason but have asked Mike to delete.

Remaining profiles are very confused as a user last year went thru deleting Abouts and swapping the names of the profiles. Luckily she seems to have only done this to the siblings so by looking at the spouses' names i'm slowly restoring to previous status with a little bit of sourcing at the same time.

Johannes Quackenbosch needs his Birth and Death Dates Added Birth: September 23, 1942. Death: May 26, 1720.

Do we have any evidence for these dates?
Birth records are almost unknown for this period, a baptism record may exist.

If we can find a marriage record there's a good chance it would list his age.

As for a death date, they're pretty rare too, unless he died in some specific event, even if we find a probated will that won't usually list the exact date of death.

On Johannes Quackenbosch Father, Pieter Pieterzoon Quackenbosch website it telles the Date forJohannas Birth: September 22, 1642, Death: May 26, 1720. Please look it up. Ki nd Regards, Arlis Taylor

_IF_ FindAGrave has a photo of a tombstone then it is a source, though that assumes whoever made the tombstone had accurate data.
Sometimes users upload documentary evidence to FindAGrave.
Neither case applies for this profile.

I am aware that there are dates in the About of the profile.
Where do they come from is the question.
Why do you believe they are accurate?

I’m assuming you are all aware of this book? Soft copy here. I have an original at home.

I’m descended from:
Alonzo Quackenboss, b. 22/Oct/1819; m.
Gen 9: Margaret Quackenboss, m. William Hutchinson on 19/Oct/1865
Gen 10: Cora Elizabeth Hutchinson (Collens), b. 1866
Gen 11: Marjory Hutchinson-Collens (my great grandmother)

Written in 1909.

I think the problem is that there are quite a few Pieter Quackenbusch (earlier ones are accurate as Quackenbos), and so some of the children may be attributed to the wrong Pieter, so some may be in fact correct, just two generations out.

No worries - the book goes back to the 1500s, the ancestors I provided are an example they go back to Gen 1. I suspect the 60 year gap refers to grandchildren for the subject of interest.
