My surname is Martin but I have no connection with you. However, the name caught my eye and so I had a look around... I found the 1930 Census and it gives Francis still working at the Cotton Mill, Fall River. ...By the way, his wife's name is Virginia.
Francis Martin aged 46
Virginia wife 36
Hard to make out but I think it says he came to the USA in 1914, or it might be 1911. I had a look for him on the ships passenger lists for the period between 1909 to 1914 but couldn't find him.
Maybe the ships passenger list only used F. Martin, which would make it harder to find him.
Hope this helps a little,
