    O. Henry was a pen name used by an American writer of short stories. His real name was

William Sydney Porter. He was born in North Carolina in 1862. As a young boy he lived an

exciting life. He did not go to school for very long, but he managed to teach himself every

thing he needed to know. When he was about 20 years old, O. Henry went to Texas, where

some money went missing from the bank. O. Henry was believed to have stolen it. Because

of that, he was sent to prison. During the three years in prison, he learned to write short

stories. After he got out of prison, he went to New York and continued writing. He wrote

案情：杜晓雨与章伟系夫妻，二人同住天津市塘沽区无线电厂家属楼，但在老家唐山市古冶区有平房6间，由其长子章云居住。2006年杜晓雨夫妇遇车祸双亡。老人的女儿章霞已出嫁，住天津市。老人的次子章雨(17岁)于 2009年考上唐山市的某大学，因该大学离章云住处近，章雨便要求章云之妻张丽将父母的遗房腾出一间由自己住。张丽说：“章云因犯罪已被判刑五年，不在家，自己不能做主；并且有 4间房已出租给了方某、刘某，租期未满，不能腾房。”为此发生纠纷，章雨便向某法院起诉，要求分割父母的遗房。
某法院受理案件后，在审理中发现除章云、章雨二位继承人外，还有老人的女儿章霞。经法院通知，章霞明确表示放弃继承权，不参加诉讼。在法院对案件第一次开庭审理后，案外人于某找到法院，说章云夫妻现住的6间房是1984年其与死者杜晓雨共同经商时共同出资购买的，自己有一半的产权，并向法院提交了购房时二人共同签名的房契。
问题：
1.本案应由哪个法院管辖说明理由。
