Hello,
it's a good surprise for me to have 2 answers fastly after posting my message and I really thank you to help me by giving me your advices.
Unfortunately I understand that the death record will not give me the missing informations I'm searching.
In the doubt I will pay for this record.
For you information, In France we don't have a national database to find the different births with only the date and even with a family name.
we have to know where the person is born.
If it's more than 100 years, you can read the record Online in each departement (County) and it's a very big advantage (I found some ancestors in the 16th century).
If it's less than 100 years, you have to contact the birth town and give the exact name and date. After they send you an official paper by mail or Post.
In the meantime I realise that I paid "for nothing" on the site UKCensusOnLine

because the same informations can be found on FAMILYSEARCH.ORG for free and I know now with this last site that Mr MEDAK and Catherine LAKERMANCE married in 1963 in Los Angeles California.
ANOTHER TOPICI'm also searching the marriage of my wife's ancestors who married in England in 1849 and died in France at the end of the 19th century.
The man John MC CORMACK who was born in Dublin in 1819 worked to build the Railway and moved to France with his french wife to build the line between the town of Rouen in Normandy and Paris.
I will contact the site GRO to get the birth record of their daughter Ellen Mc CORMACK born the 4th of august 1850 in shefford.
But how can I get the content of the marriage of John Mc CORMACK and Apoline Rosiline FOLDRINE (in fact Apoline Rosalie FOLDRAIN) with these informations below because it seems that the GRO site doesn't provide marriages records or I missed something ?
