Came across this and am helping someone with similar match
Turned out that their birth father had a daughter the same age as the testees mother so although he is in his 50s he has /had cousins aged 80-95

In genealogy Generations aren't measured by years but by descent

3 similar matches
1 knows they are half cousins thru legitimate half brothers from a second wife but the 3rd is an adopted so knows the 1st match is a half cousin shares grandfather doesn't know if the second match is her half sister or full cousin
Depending which of 3 brothers is her birth father ..to complicate matters 2 are twins !

Re generation slip, I have a relative whose first and last child were born 42 years apart.
So there is a nephew who is 20 years older than one of his half aunts.

re generation slip

My wife's nephew is the same age as his (youngest) aunt but probably more common an event with second marriages. My friend's uncle is 2 years younger than my friend

My wife and I are descended from the same couple but are two generations apart when calculating the genealogical relationship

It can also happen when 1 sibling in a family married late. My eldest cousin was 17 years older than me (I am an only child).

Paternal grandparents had quite an age gap and multiple relationships/marriages.  My half aunts and uncles span more than 50 years from first to last. The oldest was born in 1883, my grandmother born in 1890 and I came along in 1966. It's fair to say I don't get many decent matches on that side as removed half relatives often fall in the zero cM bracket.
