Below quote in Russian is from 1817, so who knows how many Slavs have been assimilated to identify as Moldovan since then. This explains logically why some results are visibly very outlying.
For example I found this village today in the Centre of the country, which is 99% Moldovan.

However among surnames, pure Moldovan ones are less than 10% (blue).
Unsurprisingly, the village is correctly classified as Ukrainian in the map from the Russian Empire's 1897 census

"Административная русификация Бессарабии совпала по времени с формированием в Пруто-Днестровском междуречье новых зон этнического расселения как пришлых «новоселов», так и природных жителей региона. На юге области селились болгары, гагаузы, немцы, русские, малороссы и евреи, в центре обосновались в основном молдаване, а на севере - молдаване, русины и малороссы. "
