Many problems with the table design ...

> GradYear text(12),

Nonsense, should be smallint unsigned.

> Email varchar(25),

Email addresses can be 127 chars long.

> ChangeDate char(12),

Yikes, should be type DateTime or Timestamp

> DeceasedDate char(12),

Should be type Date.

> Obituary varchar(40)

If that's supposed to hold URLs, it's too small.

Slapdash table design like that leads to data errors and poor performance. Take a bit of time to read about relational databases, work through a few web tutorials on the subject, then work through the opening chapters of the MySQL manual.

> 1) Loading Schemas takes about 1 1/2 minutes.
> 2) Loading Tables takes about the same time.

Sounds like a severely underpowered or misconfigured system. Let's start with what version of MySQL are you running, What is the OS, how much RAM is there, what is innodb_buffer_pool_size?
