Now I used gdisk to set things up so likely that is where I will need to start - - - hmmmmmmmmmmm.
Has anyone done anything like this in the somewhat recent past?
(Wondering if when disk is partitioned that mdadm will happily absorb that disk into the array. Likely will need another reboot too!)

I use parted or fdisk, I am not familiar with other tools. In the end, what matters is that the partition(s) on the new drive match (equal size or larger) the existing partitions.
The drive has not yet been partitioned. The disks (in the array) were partitioned to be just one large partition (whole disk).
You will then have to tell mdadm to use the new partitions. It will not "just use them".
As Lennart asked; Show us the output of 'cat /proc/mdstat'.
# cat /proc/mdstat Personalities : [raid10] md0 : active raid10 sdc1[0] sda1[3] sde1[1] 1953518592 blocks super 1.2 512K chunks 2 near-copies [4/3] [UU_U] unused devices: <none>
Also, please share the output of:

In the process of installing the new hard drive I did not label the wires from the existing setup when I was removing the wires. (I know better just didn't think first!) The new number schema doesn't seem to be causing any difficulties. Should I be trying to change things back to the sda - d raid and e/f being for the system drive and RAM drive? Thanking you for your sharing and insights!! Dee
