Honestly, the absolute easiest way is to register them as children, etc. even if they aren't normally related in this manner--that way all transaction processing is handled for you. Alternately, check out the MM .NET Dev Guide topic "Working with Transactions". It shows you how to manually handle transactions. You can also manually register one object to handle transactions with another object by doing something like this:

parentObj.TransactionStateChange +=
	new mmTransactionStateChangeDelegate(childObject.TransactionStateChangeHandler);
