Not the family I was looking for, but this census return amused me. Surely naming your children Cain and Abel is tempting fate!

I suppose a Spike Maker does what it says on the tin, but not an occupation I'd come across before.
Since the industry was founded a railroad spike, or some type of fastening device, has been employed to hold the rails firmly in place to a tie, or some other form of lateral support. The entire track structure includes the rail, tie, tie-plate, and ballast system all of which have a very important and specific function. The earliest spikes were simply crude nails and within today's modern industry the most common type has been in regular use since the early 1830s (when used in conjunction with wooden ties). In addition, following the development of concrete ties specialized clips have become common, which essentially perform the same function but appear nothing like the typical spike.
