Hello Keri, I see that you have come across the meaning of our name, unfortunately a doctor that helped me once was not so polite and when he stopped laughing, told me that the name Billen translated as "Bum cheeks"! a sort of "double dutch" eh!. Incidently, I have unknown relatives in Manchester, their grandfather was my uncle George now deceased,ring any bells ? I must have sold many of your products over the years, as one of my lives was in electronics etc.
Hope to hear from you , best wishes to you and yours , Brian.
