Dear Suanj, I'm going to write an update.
I was finally able to obtain Martino's baptismal certification. He was born in 1824 and not in 1813.
But best of all, I was able to contact an Italian relative, Carlo, a descendant of Giovanni Battista Bottino, Martino's brother.
I believe that all of this ...

I found a marriage of Angela Maria Francesca BOTTINO, 20 old on 1842 daughter of Leonardo and Cecilia Demoro... now by this record the maiden name of Cecilia is more readable... https://antenati.cultura.gov.it/ark:/12657/an_ua212682/LeMV39l

I keep looking for more information about Martin Bottino's family in Oneglia and I found the marriage certificate of his brother Giovanni, with Cattarina Ghighlielmi in 1838.
there it is confirmed that he is the son of Leonardo Bottino and Cecilia Demoro, although she had already died that year ...

Hello! I have some news after some time. A cousin obtained in Brazil the marriage certificate of Martino Bottino in 1853
There he says two very important things:
- That Martino is a native of Génova
- The mother's name is 'Secilia Da Mora' (Cecília Demoro)

At the same time that I investigate here, I am also following the track of Martino in Uruguay and his possible relationship with Giuseppe Garibaldi and the Italian Legion in Montevideo from that time there are several Newspapers written in Italian, because the Italian colony in Montevideo was huge ...

I really appreciate the effort and time you put into the search. The record is very interesting and while looking in it, I found a 'Leonardo Bottini' born in 1793, son of Leonardo e Giulia. Could he be Martino's father? he would have been 20 years old when Martino was born in 1813.

Thanks for the clarification, it's a shame not to have more detailed information about which town he was born in.
It is possible that he had other siblings but I do not know that information.
Almost all the records that I have reviewed are from 1860 onwards and at that time Martino Bottino was ...

hello! thanks for answering...
it is possible that the last name Bottino is a deformation of Bottini, who is originally from Menaggio in the Lake Como area?
In any case, the only source of information is what one of his sons declared on the death certificate in 1911.
