The Three of Wands is a card that relates to health, representing energy and balance. When read straight, it suggests that health in general is good and that there is a good chance of recovering one's well-being. From this point of view, the answer to the question could be affirmative, as an improvement in health conditions could mean that news of the lost relative will be recovered over time.
The Six of Wands is a card that refers to hope and a promising future. When read obverse, it suggests that something good is on the way. It could mean that your health will improve and you will get information about your missing relative. The answer could therefore once again be affirmative.
From the analysis of the tarot there emerges a rather strong tendency towards a positive answer to the question: will you ever hear from the relative? Both tarot cards show auspicious signs in terms of health and future possibilities, which suggests that the answer is Yes.
