Options for setting up savings/ deposit accounts in a group name

My siblings and I have inherited a euro cash amount and are considering placing this on short term deposit as one sum, for 6 months to 1 year. What options are there to open accounts in e.g. The Smith Family, and not in an individual's name? Quite a few of the savings account options seem to be for individual/ joint names only. Appreciate any assistance.

Would you consider splitting the inheritance between each of you and opening segregated accounts? Why do you want to keep the cash pooled in collective ownership?

Ultimately we aim to do this, but we may need a small percentage of the sum to clear a debt, amount of which is still unknown. Our thinking was until this is known, we would invest it to get the best return for e.g 6 months and to ensure that everyone benefits equally from any return. The net figure would then be split and each individual can invest it as desired.

At the same time, we are operating a small business partnership together and were hoping to also open a longer term savings account for small cash amounts in the group name, again if it is possible to do this?
