Not unless the estate was probated. My colleagues may have another answer.
If you have issues like this, you ought to speak with a trusts and estates lawyer as to how to proceed.
Ms. Johns is a lawyer although she is not your lawyer unless she has consulted with you and you have signed a fee or letter agreement confirming her representation of you. This post does not constitute legal advice and no attorney client relationship results.
The first option would be to check with the Probate Court in the county where they resided to see if the will was filed. Next you could get an estate attorney in that area to ask around, possibly using an email listserv. Also, if both husband and wife are now dead you may be able to find the wills while sifting through the inventory of their estate.

As Mr. Staub suggests, your best bet might be to contact the bar association in the county where the husband and wife resided. Ask them to send an email to members about whether any of them prepared a will for these people.
If the will wasn't probated and it was not "lodged" with the probate court, I'm afraid you may not have any luck finding the document.
Depending on a number of factors, including how many years elapsed between the husband's and the wife's deaths and whether either of them had any children, the wife's heirs might be able to recover a portion of her estate (see California Probate Code Section 6402.5 - http://law.onecle.com/california/probate/6402.5.html)
You need to consult with a knowledgeable probate lawyer as soon as possible.
