Is it possible to make a multisig wallet that requires one of the keys specifically and any of the other ones in order to sign a transaction?
For example, let's say I have a 2-of-3 multisig that has signators A, B, and C. Can I make a multisig that requires that every transaction be signed by A specifically and then one of either of the other keys?

No, but instead you can make a 3-of-4 multisig where you hold both keys A and B, then you give key C to a family member, and D to someone else(just as an example). This way you are certain that you are involved in all transactions. I presume this is the end result you are after?
That works and makes sense. – Jay Stevens – 2017-02-08T12:34:19.037
no need the "D" key. just 3-of-4 of (A+A+B+C) – amaclin – 2017-10-07T09:16:13.733

There is another solution but it removes the ability to identify who signed the second transaction. Create a 2 of 2 multisig wallet in Electrum. The first signature is yours. The second signature is done via a hardware wallet like Trezor. Clone that Trezor as many times as you want with the recovery seed.
