There are several records for a Frank Thompson, born 1859 in Houghton (I found the baptism for your Francis as nearby Godmanchester). He is married to Catherine and living in Cambridgeshire.
Can you give further details of the 1871 census please which might help locate him later?
Where is the Grandmother living in Suffolk?
