Greetings, and a warm welcome to Rootschat.
The first stage is to work backwards from what is known. Any definite information you have will be useful.
Was HOLLAND Rose's maiden name or married name? Do you know roughly when and where she or her siblings were born? If not, do you know when or where your grandfather/mother was born?
If we can track a birth registration we can help you find out the mother's maiden name, track back to a marriage to find parents' full names, then look on censuses (up to 1911) and other sources for details of the family.
I recommend using free sites to begin with (such as FreeBMD, FamilySearch and others) rather than rushing into buying subscriptions for paysites (this can be done when you have found all you can from freesites) and asking questions on Rootschat - the expertise of many Rootschatters is outstanding, and we are friendly and helpful!
All the best
Philip
