I found this for you:
When you have a conjunctive adverb linking two independent clauses, you should use a semicolon. Some common conjunctive adverbs include moreover, nevertheless, however, otherwise, therefore, then, finally, likewise, and consequently.
I needed to go for a walk and get some fresh air; also, I needed to buy milk.
Reports of the damage caused by the hurricane were greatly exaggerated; indeed, the storm was not a “hurricane” at all.
The students had been advised against walking alone at night; however, Cathy decided walking wasn’t dangerous if it was early in the evening.
I’m not all that fond of the colors of tiger lilies; moreover, they don’t smell very good.
These words sometimes show up in other parts of a sentence; therefore, the semicolon rule only applies if it helps the conjunctive adverb join two independent clauses. (See what we did there?) This conjunctive adverb rule is similar to the conjunction rule. In both cases, check that the two ideas are independent clauses that could stand on their own as sentences. If so, then you’re grammatically good to go as far as the semicolon is concerned.
