Many many thanks for making the link between stanley and leslie and my mothers father.
As it turns out, today my mother discovered a few old photographs containing a Gladys and Leslie colyer and eunice. So as it turns out, all the female births are my grandfathers half sisters, and grace went on to marry leslie and had a son gerald! The two in 1923 Gladys and grace were twins, grace sadly died in 1924. Both grace and eunice married so theres more researching for me to do there, but thanks to you I at least have the correct information. My mother is over the moon and is now throwing more questions at me than I will ever be able to answer. But at least she has a clear picture of her close relations. I've also managed to find an old colleague of stans, through his love of wine!! So I am hoping to discover some additional information there too.
Once again, many thanks.
