Is DNA testing relevant and useful in my search ?

Hi everybody !

I’m looking for informations if a DNA testing could be useful in my search : 

- It was said in my family that one of my ancestors, Louis Roussel emigrated to America with his youngest son.

- he had a son, Gustave Joseph, in 1874. I could not find any younger child (his wife died in 1879). I could find his birth certificate.

- in the familysearch.org site, thanks to the family tree posted by another member, I could find some informations about a man called Gustave Joseph Roussel born in 1874 in France and died November, 1st, 1936 in NYC whose father was Louis Roussel. This man had 5 sons (Robert, Gustave Joseph, Charles, Louis and Arthur).

These elements lead me to think that the connection between Gustave Joseph Roussel I found (born in 1874 in northern France) and Gustave J. Roussel who died in 1936 in NYC could be a good lead. But I have no proof.

I could find at least one living descendant of one of the 5 sons of Gustave J. Roussel till now.

With this lead, If I set the hypothesis that we share the same ancestor, this man would be the grand grand son of Louis Roussel, and my mother would be her grand grand daughter.

My idea is to do some DNA testing on the grand grand son or and daughter OR one generation down (grand grand grand son or daughter) OR a mix between these two options.

Does DNA testing could answer to the question : are we relatives ?

Would it be reliable ?

Thanks for your help and

Regards from France.

The trouble is that dna testing was made illegal in France… but immigrants could test and see what it shows. Ancestry is more beneficial mostly for older British families, and more recent immigrants (150 years) with roots in Europe could have more success with Myheritage and Familytreedna (there are haplogoups and x-dna).
