In my tree I have three sisters who married a father and son - very confusing - it took me a while to figure it out since the men shared the same name!
In 1864 the eldest sister aged 38 married a widower aged 41 with a son age 15.
In 1875 the middle sister aged 38 married the son - by then aged 26.
In 1877 the middle sister died at 40 - the son moved back home.
In 1889 the eldest sister was widowed.
In 1897 the youngest sister (by then age 57) married the son who was by then age 48 - something tells me he preferred older women!
So all three sisters married late and none of them had children. Given the potential for confusion, it was probably just as well
