Yes, this is a book you need to write!
My uncle wrote a family history based on his genealogy investigation, after he had retired from Boeing as an aerospace engineer. No one outside the family and a few friends would be much interested perhaps. That lead to him writing books geared towards teenagers, but very fun reading for adults. Excellent books for family values and teaching kids in a fun way. He has his third almost ready to publish. I say this, because he is passing on his values to whoever reads the books. You in effect an historian just like he is.
