i would like to find out about a certain artist?

Question

i have an oil painting giving to my mother-in-law many years ago,the signiture is NEWTON.It's of three women and a child all done in dots of paints

Answer 1

The technique you describe is called pointillism.

I searched for artists with the last name Newton and came up with this:

Ann Mary Newton[1832-1866]
Gilbert Stuart Newton[Canadian/British, 1794-1835]
Helmut Newton[German/Australian, 1920-2004]
Lilias Torrance Newton[Canadian, 1896-1980]
Sir William Newton[1785-1869]

There's also Francis Newton Souza.

I might be able to find more, but would need to see the painting.

From here you can look for both the artists and the word pointillism to narrow your search. Good luck!
