You will need to give more info for anyone to help you:
* Was Asher the official first name (ie the name they were registered with at birth) of your father and your grandfather, or was Asher a second name?
* Do you know of any other first names for your father and your grandfather?
* When you say they passed 'some years ago' can you give an approximate date for your father, and for your grandfather?
* Where was your father born? Your grandfather?
*Any other family details / names / places etc
I ask these questions because an initial search shows NO births and NO deaths in England & Wales for an Asher Basford (or similar) or an Asher Pell(e) (or similar) from 1837 to 2006 - hence the need for further information to be able to investigate further for you.
