Some of cases like this are CPFP (Child-Pays-For-Parent) transaction.
Being mined at the same block and the child transaction having higher fee rate the parent indicated that it's that kind of transaction.
...
However, none of the transactions in the OP are CPFP.

Thanks.

And I don't mean to clutter the thread but I bit the bullet and made a tx with a 138 sat/byte fee to hopefully encourage a miner to pick up the payment transaction 

Cheers to all, have a great week.
