Help with 81/91 Gravesend please

[oldphil]

I am researching John Lawrence Johnson born in Sweden about 1848..In 1881 census he is with his wife (Mary Ann Curle) and four children..In 1891 there are seven children still in Gravesend but different address..Between the two censuses two of the children have changed names.Minnie becomes Mary and  the eldest son becomes Thomas (or is it James)?..I cannot decipher what the child's name is in 1881..Any ideas?

Hi KG..The following census for '91 is confusing, William has only aged 6 years!.( He is sometimes known as Theodore later in life)..He was my wife's grandfather I always new him as Dick!.Confusing or what! ?.The three additions to the family between the two counts appear to be Alfred,Ada and Benjamin.I can't find The father prior to 1875 when he married Mary Ann Curle..Any ideas?

Almost certainly not the same William?

It was quite common to name a child after a deceased sibling.

Yes..Never thought of that angle..Thanks..Looks as if "my" William was born 1885.Need to check on infant death perhaps.
