Family member passed away and I found a 12 word seed phrase

Hi guys. I have been hodling since 2016 and recently found out my brother also had been. He passed away recently but we never actually talked about crypto.In his emails I found a 12 word seed phrase, but no reference to a ledger etc.Does anyone know other wallets that use a 12 word seed phrase (i have only ever used a ledger). via /r/Bitcoin https://bit.ly/3hxNdlH
