sir,I have fixed my daughters marriage in june. we have shifted to our own new house.We did not perform any gruhapravesam as my father in laws one year had not been completed.we performed her engagement on jan 23rd and on jan 24th we heard my husbands chittappa passed away.There has been no contact with chittappa for more than 40 years on my husbands side.Are we still not supposed to perform swamy samaradhanai and sumangali prathanai?we have not done any homaman in our new house also.As we do not know who is our kula deivam we have decided to have ishta devatha as Balaji venkateswar perumal.Am i doing right.Please clarify
