Need some clarification about Arora gotras

My dad says that our gotra is Rajwaddha (this is the way he pronounces it). He says this is the name of our gotra in Multani presumably. However though, [this website](https://www.arorakhatri.com/gotra-list-character.php?character=R) tells me there isn't a gotra called Rajwaddha (ਰਾਜਵੱਢਾ/राजवड्ढा). That being said, I did find some similar gotras in name like Rajabadha (राजाबाढ़ा/ਰਾਜਾਬਾੜ੍ਹਾ), Rajvada (राजवादा/ਰਾਜਵਾਦਾ), and Rajveda (राजवेडा/ਰਾਜਵੇਡਾ). If anyone has any idea on this subject, which one of these matches my gotra?
