Interesting question. The deed is first filed in the reception record which is the legal record for the county. Tract Books and Grantor/Grantee Indexes are a convenience provided by the Clerk and are not the legal record. Ask yourself the purpose of the deed. Is it to inform interested parties or to provide color of title on unknown properties?
You can make an any and all grant in the deed for notice purposes. Depending on the Trust document, you may be able to appoint a Power of Attorney for any unknown properties. Best practice is conveyance by a proper legal description. I will be interested in the responses
