Where is Leo Alfred Myers in 1910?

I don't know enough about records available in the US to help specifically.....however a few thoughts...which you may or may not have looked at...he would have been 20 years old in 1910, so in 1920 he was an Ind, machinist, shipyard in 1930 Ind, engineer, shovel......is it likely he was working in the ship yards on census night 1910, or on board a ship ( trial/testing) and out at sea, if so and according to census rules in the US at that time ( ?) which may or may not be the same as the UK could it be he was just forgotten, left off, not required as not at home or are there census for ship yards/ test sails....have you found the rest of his family in 1910? Are the 1910 census complete in that area of the country?................................…
