The first ones are definitely Harlequin probably l early 2000's I think.  None of them new than maybe 5 yrs at least, could be as far back as end of the 90's though  I think.  LOL  

First one I believe was Harlequin Desire, His wife died left him with two small girls (I don't think they were twins), her husband died leaving her no children, she always wanted a family and they are friends.  He needs a wife, someone to be there for his girls, she's been babysitting for him but now he wants something more full time (for the girls of course).eventually they get married, with the caveat no more kids.  Of course eventually she ends up pregnant, and tension ensue. Until he realizes he's being an @ss and they get their HEA

The second one about the same time frame, maybe earlier 2000's I want to say it's a Harlequin Silhouette..  but again not sure

Again he's a widower I don't remember if he's a rancher or has a construction business... has 3 kids I think, older girl maybe preteen,  other two are quite a bit younger.  Can't do kids and business too, wants a wife.  Approaches long time friend who's parents are now gone, she's never married proposes a marriage just no romance, mutually benefit he gets a wife all the perks she gets a family she wouldn't get other wise, or any time soon.  She agrees because she's always been in love with him, even though he married someone else.  The usual trials and tribulations of being a step mom, but things seem to come together of sorts.  Until he gets word that some fellow was flirting with her at the diner, he comes home in a mood, the girl comes home crying yelling at her over some boy, all the while she's trying to tell him she is pregnant when he says he doesn't even know why he married her, and stalks off to go take a shower.  She decides she has to go, but leaves in an ice storm and has a wreck.

Things come to ahead in the Hosp and the HEA at the end of course

One more I am pretty sure is a Harlequin Desire, I don't remember a whole lot about it except it starts out with her telling her boss she's pregnant (one night together, possibly Christmas party?) and he responds with congratulations who's the father.  To which she informs him no one, it's her baby and she's just telling him so he can adjust to her taking time off and to find a replacement when she goes on leave.  She then says she's taking the rest of the day off, he realizes he was a tremendous jerk and tries to catch up with her, as she peals out of the parking lot he realizes he doesn't even know her address, and has to go to HR to get it.  He does show up at her house....

I don't remember the rest after that.  I thought I did, until I realized I was mixing up the begining of this one with the end of another lol.

Last one I really am not sure if it is a Harlequin or one of it's properties like MIRA or such.  It is a romance though.

Yep it was Instant Husband by Judith McWilliams.  Thanks!

Woman wanting a new/better start I forget why nothing major though.  He wants a wife but not the romance, he's getting his daughter (young teen) and thinks all would be better with a woman, plus the place is kind of run down it's just him and an old guy don't remember if he's a relation, friend, or hired hand.  But he's cranky, and not a fan of women in general.  She answers his ad I believe in the help wanted or classifieds... anyway she arrives they marry, civil service.  At one point she falls through the floor in the kitchen, there are quite a few humorous incidents, they end up staying in a cabin while the house is renovated, a one room cabin.  Eventually the kid arrives, who all in all is smarter than the two adults, and works slyly pushing them together so they realize they care/love each other.

At some point she finds out or suspects she might be pregnant, mentions something about not feeling well, needing to see a doctor maybe, or something and he of course is a butt an says something along the lines of dear god anything but pregnancy, never want to go through that again or something insensitive.  She decides she has to leave, the teen whom she thought was her friend offers to book her flight online while she packs if she's determined to go, and off she goes.  He eventually notices she's not home from the doctors and the kid tells he she's gone and why, but tells him he can catch up with her because she gave her a ridiculously long lay over in Denver or somewhere.

So he takes his jet (seems he is uber loaded) and catches up with her, HEA.

So any ideas of titles?  bonus if you have them on your shelf I'll order them from you!  

That last one sounds just like Instant Husband by Judith McWilliams.

I can't quite come up with anything that fits.  For the first one (the guy whose wife died and left him with 2 kids) I was thinking one of the Brannigan books by Leslie Davis Guccione but the one brother that had kids, the romance didn't go like that.  Then, I was thinking Wife, Mother, Lover? by Sally Tyler Hayes but it's not that either, the kids are twin boys and the heroine is the sister of the dead wife.

The other 3 almost sound like Diana Palmers but I can't think of anything that fits right though.

Thanks Bronwyn, that might just be it.  I'll have to order it to know for sure but it seems pretty close if it isn't.

No, none are Diana Palmer books, that much I'm sure of.

Thanks for the input though.

I wanted to point you to a lovely search site:

Romance Reader at Heart

Just pop some keywords about the stories into their search engine and they'll come up with lists of books as possibilities.  It can be pretty time consuming (I get pretty addicted when I'm looking for something) but sometimes you can remember enough to search it out there.

I don't think any of them fit perfectly, but they sound very similar to Linda Howard's Sarah's Child.

Thanks Sarah, I'm went there, the search engine isn't really that great lol  I'm going through them a bit at a time but by the time I get through I may be too old to read them lol.  No way to filter out regency, historical and looks like the search includes any book that has just one element.  The search engine at Harlequin and amazon are a bit better but I went though all  the books on both those sites, so far nothing.  

My next stop is bookslueth, but again lots to go through.

Renee, no not the Linda Howard book, he lost his wife but no children.  Thanks though.

I'll keep looking but appreciate all the input so far.  Thanks.

I adore Sarah's Child and that's definitely not one of the books described.
