Abkovich - origin from where?

[Vasteras]

Hi !

A relative of mine married a man with the surname Abkovich, he was born
in Vilna (Vilnius) 1898 in Latvia (Lithuania) but was raised from very
young age in Moscow where his father had a tobaco factory.

He died in the USA in 1982.

I am looking for the origin of this surname, for me it doesn't sound
like Latvian or Russian.

His first names where Joseph Leland.

Hope that someone can help me.

TIA
