You can use the following code,

Account dummy = GetAccouns(); //Assume GetAccounts fills account data
var result = dummy.Memos.SelectMany(x => x.MemoRefferances).ToList();

You need SelectMany:

Projects each element of a sequence to an IEnumerable and flattens the resulting sequences into one sequence.

var allMemoRefferances = account.Memos.SelectMany(x = x.MemoRefferances);

You can use SelectMany to get all the MemoRefferances1 in Account.Memos 

var results = someAccount.Memos.SelectMany(x => MemoRefferances);
