Thank you for the information, Marie.It is very helpful. Louise was a popular name among these groups.The only one who may be the woman you are seeking was married to someone named Serra.There is no more data on her.
I can study these sheets and perhaps come up with a better answer if I had the dates of birth, etc. re Louise.There are many pages here.Such an interesting family; I see a death by train of a 2-year old and a drowning of another child in the family reservoir.They seem to have prospered nicely and a main road is named after the Amar family.
Please send me all you have on Louise and I will get back to you.
