On the 1881 Census Henry & Martha with children,Herbert, Ella ,Edith, & Linda.were recorded at 3, Adelphi Terrace, Whitstable, Blean, Kent, England.( Ada not born until 1882)
Can see baptisms for Edith,July 26th 1878 and Linda April 4th 1880. Both at St Alphage ,Seasalter. Can't see Baptisms for Herbert bn 1874 or Ella bn 1876.
Looks like Henry and Martha Married at Blean Registry office 1873 not at Church.
