I am searching for information on my g grandfather, Gustave Ericson. Here is what I think I know:
He was born in Sweden in 1846.
He married Mary Ann Williams in Notting Hill St Mark, England, 17 Sep 1876.

According the the parish records that recorded the marriage, Gustave's father's name was Nicholas Ericson. I am not sure where the father lived. His occupation is given as carpenter (this is a guess as the writing is hard to read).

Gustave's residences were:
1881 census: Battle, Sussex, England
1891 census: St Andrew, Sussex, England
1901 census: St Mary in the Castle, Sussex, England

His death was entered into the BMD records in the first quarter of 1907 and listed as being at Hastings, Sussex, England

Along the way he had 6 children between 1878 and 1888.

I need help with:
1. Gustave's date and place of birth
2. His emigration date from Sweden
3. Where he live in Sweden prior to his departure
4. Where he live in England up to the time of his marriage

Thank you for any help / suggestions that can be provided
