Edward appears to have had (at least) 13 children as follows:

Child	Mother	Mother's maiden name from GRO
Jane	Ann
Mary Ann	Ann
Sarah	No baptism found
Rebecca	Alice
Edward	Alice
Eleanor	Eleanor
Ann	Ellen
Thomas	Ellen
Susan	No baptism found	Cowderoy
Mark	No baptism found	Cowderoy
Alfred William	Eleanor	Cowdery
John	Ann (I believe this to be incorrect*)	Cowdery

After fathering all these children he married Ellis Cowdery!

A number of family trees on Ancestry believe Alice, Eleanor and Ellis to be the same person. There seem to be good reasons to support this:

• I can find no trace of a baptism for Eleanor Cowdery or Ellis Cowdery but there is a baptism in 1797 of Alice Cowdery whose father, John, was a cordwainer.
• The mother's maiden name in the case of some of Eleanor's children was Cowdery or Cowderoy.
• An Alice Frost was buried in 1882 aged 84 (=1797/8) although the GRO (typed) record says 81. She is Ellice aged 72 in the 1871 Census living with her son Alfred and his wife.
• If Edward and his first wife, Ann, separated (rather than Ann dying) this could be why he did not remarry until much later (but I have not traced a likely death record for Ann).

*The mother's maiden name indicates that John belongs to this family.
