Simplify the following text for a Grade 7 native English-speaking person.
Original: Martyrs Marcellinusâ s and Peterâ s bones , which had been stolen in Rome , were transferred from the basilica in Steinbach in the Odenwald to ObermÃ 1\/4 hlheim , soon leading to a change in the communityâ s name from ObermÃ 1\/4 hlheim to Seligenstadt ( â Blessed Onesâ Townâ in German ) .
Simplified: In this time also the name was changed from ObermÃ 1\/4 hlheim to Seligenstadt , because people brought some holy bones to the town .
