I believe our families are both related to George Washington. What a surprising occurrence!

I believe our familys are both related George Washington. What a surprising ocurrence!
Is the spelling right on either sentence.

The plural of family is families.

So the first sentence is right.

First sentence only

There are at least 3 errors in the second, but the first is correct. (families, related to, occurrence)

The correct spelling for the first sentence would be:

"I believe our families are both related to George Washington. What a surprising occurrence!"

In this sentence, all the words are spelled correctly, and the punctuation is also correct.

The second sentence, "I believe our familys are both related George Washington. What a surprising ocurrence!", contains a few spelling errors. The correct spelling should be:

"I believe our families are both related to George Washington. What a surprising occurrence!"

Here are the corrections to the errors in the second sentence:
- "familys" should be "families"
- "related" should be "related to"
- "George Washington" should be "to George Washington"
- "ocurrence" should be "occurrence"

By comparing the two sentences, you can see that the first one is correctly spelled, whereas the second one has some spelling errors.
