Long Honeymoon in Norfolk: 25 years waiting for a child

In the course of finally investigating my maternal line, having failed to notice I even had one...

I came across the Long family of Spooner Row, Norfolk. Elizabeth Long married in 1879 at the parish church, age 19, and she comes from the same Norfolk uterus as I do, so is my uterine relative. (Thus Edmund ap Tudwr was a uterine brother of poor Henry VI.)

She has no children listed in the next THREE censuses until Alice Martha, her daughter, arrives in 1904. That's a 25 year wait. The GRO index confirms there were no other births from this couple.

Exhausted by his endeavours husband Walter Green dies and is pegged out five years later.

Around the same time, the ageing reproductive equipment of Elizabeth's father, 60+, grinds back into action, courtesy of a much younger second wife.

Alice was recorded as incapacitated in the 1939 register, which may indicate she was living with Down's, not sure.

I'm curious to know if anyone else has seen such a long gap from the wedding to the birth of a first child.
