I guess it depends on how you count! I usually count combining duplicate spouses and duplicate children as one step when I guess you could count it as 2!
Wouldn’t it be wonderful if we could get everyone to combine thoroughly and carefully before looking at submitting a name to the temple!
I notice there is an updated knowledge document in the Help Center on Combining. KD 100986 ( you can search in the Help Centre just by putting in the document number if you have a list of favourites or by entering key words – in this case “combine four ways”). You can print knowledge documents (To print this document, place your mouse pointer here, right-click, and choose Print Target) or copy and paste the content.
This looks like a thorough document. Hope it is helpful.
