Hello. Some linguists have classified Southeast Asian into several families Australoasian, Austronesian, Mon-Khmer etc. , but I agree with those who claim that nearly all of them can be lumped together into a large superfamily which they call "Malayo-Polynesian". Some linguists and anthropologists place the earliest origins of this group in South China, some in Thailand, some in India, one researcher even as far west as what is now Turkey. More research needs to be done here. Almost all agree, however, that the ancestral speakers of this group were a farming people.
Just a casual reading about various Southeast Asian languages turns up random similarities from language to language that leads to a network of similarities, nevertheless, ponting to a common ancestor. The Malayo-Polynesian group is not unlike the Indo-European group which also spans half the globe. It stretches from Thailand to New Zealand and from Madagascar to Hawaii and Rapa Nui (Easter Island). Keep in mind, also, that we are talking about languages whose common ancestor was probably spoken at least 5,000 years ago.
Here are some of the similarities:
1) Fish - Malayan & Indonesian ikan, Vietnamese cá.
2) River - Malayan & Indonesian sungai; Viet. sông
3) Tree - Vietnamese cây, Ilokano kay
4) Star - Ilokano bituen, Tagalog bituin, Samoan fetu

8) Ear - Vietnamese tai, Tagalog tainga, Samoan taliga
9) Fat - Vietnamese mâp, Tagalog mataba
10) New - Vietnamese mo’i, Thai mai, Laotian maii,
11) Old Person - Vietnamese gia, Thai gaa
12) Heart -Vietnamese qua tim, Thai & Laotian huajai
13) Onion - Vietnamese hánh, Thai hua hawm
14) To wash - Vietnamese r’u'a, Thai & Laotian lahng
Cambodian liang
15) To see - Vietnamese nhin, Thai & Laotian hen

Finally, I also leave you with someone else’s opinion on the whole subject:
