Please read my previous posts on HPV- you can click on my name and view previous posts.
I did post a reference by the Mayo Clinic that HPV is the cause of most cervical cancer, and another reference that "most" was an estimate of 99.7% of cases in one study, so HPV is the cause of the great majority of cervical cancer cases.

Regarding HPV and heredity:
As I understand it, HPV is similar to HIV in infection, though it can be caught by genital touching rather than just sexual relationships. Thus, HPV can be passed from mother to fetus, though that would be unusual. Also, you could inherit a weakened immune system, which might make you more likely to get a persistant strain of HPV. However, if you have made it into your 40's without having persistant HPV, the odds of getting it are very low unless you are extremely sexually active with people who have HPV (in a similar way to HIV). Thus, in that having a brother or sister with HIV would not necessarily imply that you would have HIV, neither would a family member with HPV imply that you have HPV, unless you have had it since birth, but you could inherit a weakened immune system.

Here is a reference that I posted earlier about HPV- please get tested for the strains mentioned before making a decision about whether to remove your cervix.
Here's the HPV statement from the Netherlands:
A distinction is made between high-risk HPV types (16, 18) and low-risk HPV types (e.g., 6/11, 42, 43, and 44).1
The low-risk HPV types 6 and 11 are associated with
genital warts.
The results of studies of the relationship between high-risk HPV types 16, 18, 31, 33, and 35 and the prevalence of endocervical intraepithelial neoplasia or cervical carcinoma in situ are unequivocal.
Specifically, HPV type 16 is often found in such association and has the strongest connection to cervical intraepithelial neoplasia (CIN).
Genital warts in women do not appear to indicate an elevated risk of genital carcinomas.
