ball Migration from England to the United States
This is an interesting story filled with more questions than answers. As of June 28, 2013 we still have no imformation on when James made his voyage to the United States. (Based on the birth of Frederick, our best guess is James' arrived somewhere between April 1864 and May 1866.)

ball (1866) The family crossed the great ocean without James…
I do not know how many people have searched immigration and ship records looking for the arrival of the family into the United States of America. However, I can tell you that I have been personally looking for over four decades. This little piece of the puzzle has literally been like looking for a needle in a very large hay field.
On 16 May 1866, aboard the ship Southampton, we find the following information:
Exhibit #1
It is amazing that we have found this information.
  The last name was recorded wrong on their arrival and James did not make the trip with them.
  We now know beyond doubt that Amelia arrived in the United States of America.
  We can see on Amelia’s record that she is making the trip to be with James.

Trivia train
Six years after the groundbreaking, laborers of the Central Pacific Railroad from the west and the Union Pacific Railroad from the east met at Promontory Summit, Utah. It was here on May 10, 1869, that Stanford drove The Last Spike (or golden spike) that joined the rails of the transcontinental railroad.
The first emigrants to come all the way to Ogden by rail arrived June 25, 1869, over the Union Pacific.
Just one week after the golden spike was driven to celebrate the completion of the transcontinental railway, ground was broken for a branch line from Ogden to Salt Lake City, the Utah Central Railway.
On a cold day in early January 1870, a gathering of fifteen thousand people in Salt Lake City cheered the completion of the Utah Central Railway.
