Hi tim, just seen your earlier message. I have found your family I think - I have a Charles born 1878. His parents were John Formby and Catherine norris - if that is correct then you are in fact the descendants of the Aindow Lifeboat crew. John was the captain of the Lifeboat. There is a great book about the history of it
Britain's First Lifeboat Station: Formby, 1776-1918- you can buy it on Amazon (the authors (by Barbara & Reginald Yorke)- I have met at a walk around the remains of the Lifeboat station in Formby that was held last year)
john Aindow born 1898 was the son of John Aindow and bridget Sinnott and was indeed the nephew of Charles.
