Should a Sinhala choice read a house name ending in -ge as part of the family name? (Piyumali Sandareka Arachchi Mudiyanselage gives middle 'Sandareka Arachchi', family 'Mudiyanselage') #1247

Many Sinhalese families carry a house name (vasagama), often ending in the genitive -ge, "of the house": Dissanayake Mudiyanselage, Ratnayake Mudiyanselage, Balasuriya Arachchige, Matarage, Piyadigamage. In the official full form it comes FIRST, before the given names: Dissanayake Mudiyanselage Ariyadasa, shortened to D. M. Ariyadasa. People who reorder for a Western form write it LAST. Either way it is one family name of two words, and the parser reads one word by position (measured on master ccaf6ad):

How often (2026-11-08):

• ORCID, Sri Lanka, the records the default reads differently from the holder's own boxes: 593 hold a family box of two or more words, one of them a -ge word (Arachchi Mudiyanselage, Abeysooriya Patabandige, Bamunu Arachchi Pathiranage), where the parse keeps only the last word. The -ge words in those boxes: mudiyanselage 88, arachchige 83, gamage 70, liyanage 33, hewage 22, kankanamge 19, pathiranage 14, arachchilage 13, guruge 12. Another 662 hold a family box of two or more words with no -ge word (Mohamed Nafrees, Beragama Arachchi, Rajapaksha Pathirana).
• parliament.lk's list of past members writes most names inverted, Hon. Family, Given Names, M.P. (580 of the 657 I read). In 136 of the 580 the part after the comma holds a house name: 106 before the given names (Attanayake, Attanayake Mudiyanselage Rambanda) and 30 with nothing else (Ariyadasa, Dissanayake Mudiyanselage, where Ariyadasa is the personal name the member was known by).

So the comma doesn't mark the family here either. The -ge ending is a script-free marker, like the Mongolian genitive (#1237) or the Persian زاده (#1152), and like them it would be a language choice's rule, not a default: Gamage and Liyanage are also surnames on their own.

Questions

• Should a Sinhala choice read a -ge house name, and the word before it, as one family name wherever it stands? (Before the given names: Dissanayake Mudiyanselage Ariyadasa → family Dissanayake Mudiyanselage, given Ariyadasa.)
• Or should this go through two_family_names (O6), with the -ge word as the cue that two family words are present?
• Which field holds the house name when the person also has a surname (Herath Mudiyanselage Saman Kumara Herath)? CLDR's surname2?
