Hi sproutie1
George Kemp and Elizabeth fry
daughters and partners
I have no info as of yet for Martha and Elizabeth Kemp but
I can answer one question .
Mary Kemp was born 1816 died 1917 .
married to peter Phillips born 1815
Sarah Kemp was born 1807 died ?
married Charles cousins born ? 1807
this will narrow your search.
you may find that Horis was illegit and if he was born at sea in 1829 then there may not be a record. as they were not recorded till 1853.
Elizabeth or Martha may have had him out of wedlock and he may also go under a different surname as both martha and elizabeth may have remarried.I had this happen with a great great grand father on the other side of my family. so took a while to find him.
the Kemp's go back to 1605 so far in that area .as you say there are loads of us.
