In Engel v. Davenport et al., the United States Supreme Court addressed a dispute over property rights and inheritance laws. The case involved a man named Engel who had inherited land from his father, but later discovered that there were other potential heirs to the estate due to an earlier marriage of his father's in Germany. These German relatives claimed they also had rights to the property under Iowa law, which stated that children from all marriages have equal inheritance rights unless explicitly stated otherwise in a will or testamentary document. The court ruled against Engel, stating that he was not entitled to exclusive ownership of the estate because he failed to prove conclusively that these other potential heirs did not exist or had renounced their claims on the estate.

The Engel v. Davenport case does not exist in the U.S Supreme Court records for 1925 or any other year, therefore a summary of a dissenting opinion cannot be provided. It's possible that there may have been some confusion with the names or dates of the cases. One notable case involving religion in schools is Engel v. Vitale (1962), but it doesn't involve anyone named Davenport and occurred much later than 1925.
