Binder Family 1871

Also found at this address were:

• Thomas J. Hammond, aged 57, Engineer, born Sheerness, Kent
• Amelia Hammond, aged 46, born London
• Amelia's BC shows these to be Amelia's parents but her MC shows her father to be Thomas HENRY Hammond. Also shown on her MC is Thomas Shaw Hammond as witness. So we have three males named Thomas Hammond: Thomas Henry; Thomas Shaw; Thomas J.
• Thomas and Amelia are too young to be the grandparents of 20-year-old Amelia. On the other hand, the fact that the women are both named Amelia suggests they are mother and daughter. I accept that Thomas John is her father.
